I had a question regarding karate.robot do we have any method or function to shut down or close or quit Karate.robot session like driver. quit or close?
it seems some threads are occupied getting following error many times:

No, we don't see a need. You typically start the Robot instance and it stays up until the end of your entire suite. Maybe you should try install the JDK 64-bit or 32-bit.
You are welcome to contribute code to improve anything if required. So far no one has reported any problems like this. Maybe you are trying to do things in parallel threads which is not supported. Provide a way to replicate if you can: https://github.com/intuit/karate/wiki/How-to-Submit-an-Issue
EDIT - one area you can help us investigate is if we need to do more to release JNA resources after a Scenario in this method.
Also see this answer: Java JNA: JRE crashes after application completes
my java application crash with coredump
coredump say terminated with signal 6 but hs_err_pid file was different:
it makes me confused
SIGSEGV is caught and handled by the JVM itself.
In response to SEGSEGV JVM writes hs_err_pid.log and then terminates process with abort() call to force core dump. abort() call results in SIGABRT.
Iam facing JVM Crash cosistently while enabling hotdeploy (USING below java options on starting up JAVA_OPTS -Xmx4096m -XX:MetaspaceSize=512m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=crash -XX:ThreadStackSize=512 -XX:+UseConcMarkSweepGC -XX:ParallelGCThreads=5 -XX:NewRatio=2 -XX:+UnlockDiagnosticVMOptions -XX:-UseLoopPredicate -Xdebug -Xrunjdwp:transport=dt_socket,address=$DEBUG_PORT,server=y,suspend=n -XX:NewRatio=2 -Dspringloaded.synchronize=true JAVA_OPTS=`echo $JAVA_OPTS -Dspringloaded.synchronize=true -javaagent:springloaded-1.2.1.jar -noverify

I've noticed both -javaagent and -noverify in Java options list.
It looks like springloaded agent generates invalid bytecode, while the bytecode verification is explicitly turned off. No surprise, this may lead to unpredictable results including JVM crash.
This is not a JVM problem, but most likely a bug in springloaded agent. Try to remove -noverify option.
-XX:-TieredCompilation may also work around this particular problem, but don't expect application to work correctly if the bytecode fails to pass verification. It's better to stay away from the buggy agent libraries.
4.2.1 Crash in HotSpot Compiler Thread or Compiled Code
If the fatal error log indicates that the crash occurred in a compiler
thread, then it is possible (but not always the case) that you have
encountered a compiler bug. Similarly, if the crash is in compiled
code then it is possible that the compiler has generated incorrect
code.
In the case of the HotSpot Client VM (-client option), the compiler
thread appears in the error log as CompilerThread0. With the HotSpot
Server VM there are multiple compiler threads and these appear in the
error log file as CompilerThread0, CompilerThread1, and AdapterThread.
Below is a fragment of an error log for a compiler bug that was
encountered and fixed during the development of J2SE 5.0. The log file
shows that the HotSpot Server VM is used and the crash occurred in
CompilerThread1. In addition, the log file shows that the Current
CompileTask was the compilation of the java.lang.Thread.setPriority
method.
An unexpected error has been detected by HotSpot Virtual Machine:
:
Java VM: Java HotSpot(TM) Server VM (1.5-internal-debug mixed mode) :
--------------- T H R E A D ---------------
Current thread (0x001e9350): JavaThread "CompilerThread1" daemon
[_thread_in_vm, id=20]
Stack: [0xb2500000,0xb2580000), sp=0xb257e500, free space=505k
Native frames: (J=compiled Java code, j=interpreted, Vv=VM code,
C=native code) V [libjvm.so+0xc3b13c] :
Current CompileTask: opto: 11 java.lang.Thread.setPriority(I)V

Memory Detector" daemon [_thread_blocked, id=21]
=>0x001e9350 JavaThread "CompilerThread1" daemon [_thread_in_vm, id=20] :
In this case there are two potential workarounds:
The brute force approach: change the configuration so that the application is run with the -client option to specify the HotSpot
Client VM.
Assume that the bug only occurs during the compilation of the setPriority method and exclude this method from compilation.
The first approach (to use the -client option) might be trivial to
configure in some environments. In others, it might be more difficult
if the configuration is complex or if the command line to configure
the VM is not readily accessible. In general, switching from the
HotSpot Server VM to the HotSpot Client VM also reduces the peak
performance of an application. Depending on the environment, this
might be acceptable until the actual issue is diagnosed and fixed.
The second approach (exclude the method from compilation) requires
creating the file .hotspot_compiler in the working directory of the
application. Below is an example of this file:
exclude java/lang/Thread setPriority
In general the format of this file is exclude CLASS METHOD, where
CLASS is the class (fully qualified with the package name) and METHOD
is the name of the method. Constructor methods are specified as
and static initializers are specified as .
Note - The .hotspot_compiler file is an unsupported interface. It is
documented here solely for the purposes of troubleshooting and finding
a temporary workaround.
Once the application is restarted, the compiler will not attempt to
compile any of the methods listed as excluded in the .hotspot_compiler
file. In some cases this can provide temporary relief until the root
cause of the crash is diagnosed and the bug is fixed.
In order to verify that the HotSpot VM correctly located and processed
the .hotspot_compiler file that is shown in the example above, look
for the following log information at runtime. Note that the file name
separator is a dot, not a slash.
Excluding compile: java.lang.Thread::setPriority

Agree with #apangin, In the program you are doing bytecode intrumentation (-agent) but specifies -noverify. When verification is turned off, you may end up such crashes.
You should not use -noverify or -Xverify:none during byte code intrumentation.
For those of you unfamiliar with bytecode verification, it is simply part of the JVM's classloading process that checks the code for certain dangerous and disallowed behavior. You can (but shouldn't) disable this protection on many JVMs by adding -Xverify:none or -noverify to the Java command line. https://blogs.oracle.com/buck/entry/never_disable_bytecode_verification_in
Great library, works well in debug.
However, after I exported a signed application package, it crashes every time I try to fire up a chart. Just, puff!!!
I'm using sdk 19 and targeting 16 min.
Does AChartEngine have any special ProGuard settings?
Any suggestions?
Here is part of the logcat (thanks to keshav):

I have a problem with Java 1.5.0 for AIX. The error happens just when I log on with specific user on AIX (myuser). When I log on with other user java works ok.
The error come up even when I executed just "java -version" or simply "java" (of course, without quoting). I've tried executing it with the full path: /usr/java5/jre/bin/java but still fails.
There was installed the version 1.4 of java on system too. So the $PATH variable for the user contained /usr/java14/jre/bin, but I removed that value, I even uninstalled that version of java (1.4) so that just java 5 exists on the system, but the error continues.
If I execute "java -fullversion" it doesn't crash.
This is part of the error (the full output is very long):

I found the error. The problem is a line on the .profile which sets the environment variable LIBPATH:
export LIBPATH=/home/myuser/sys
I deleted that line in the .profile and java worked.
