Picked up _JAVA_OPTIONS. Invalid max heap size? - minecraft

So, I was trying to run my test Minecraft mod in Prompt as per a tutorial. In one part, I should type in 'gradlew getIntellijRuns' and everything should run smoothly. Instead, this message appears: -
I've even tried "Xmx4096m", but it generates the same message.
Invalid maximum heap size: -Xmx4G
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Okay. I solved the issue! So, I had allotted a bit too much RAM for _JAVA_OPTIONS. I tried '-Xmx1024m' and it worked brilliantly. And also, I made a small mistake in compiling the Gradle project via Command Prompt.
This is what I had typed: -
gradlew getIntellijRuns
And what I was supposed to type: -
gradlew genIntellijRuns
I found this out when I typed this: -
gradlew tasks
This command lists all available commands for the project. That way, I rectified my mistake.

OPUS Make error: OPUS MAKE: Unknown status. Stop

We are using OPUS Make in our build infrastructure. (Basically traditional make with some wrappers around I guess)
Our codebase is mostly Java and I have been making changes and building for many months now. No issues.
Suddenly, a couple of days back, when I tried to build,i started seeing this error:
OPUS MAKE: Unknown status. Stop.
I see this error no matter what I try to build. More imp - it looks like it is not even trying to actually compile my code and for some reason just stops before with the above error.
I tried doing a clean build. Even manually cleaned up all old generated build files. Still did not work.
I even tried restarting my environment itself. Restarted Clearcase. Still no use.
I see there is a way to build with debug information. Did that also make -d
However, that did not give any useful info either. Just the same line as above. I was hoping that it would give some debug logs or some error code that I could use to solve the problem.
I see there is an option: make -n. That comes out clean. But from the name, it looks like it does not even attempt to run the build itself.
Please suggest what the issue could be.
thx - Om
"Unknown status" means that a shell command in a target returned a status that make did not understand. Run with -d to see which command is failing. And debug that shell command.

SystemTap semantic error when trying to run dvorak-qwerty script

I found this repo with a systemtap script for letting me use QWERTY ctrl-shortcuts on my dvorak layout. Unfortunately, I can't get it to work, but I don't think it has to do with the script itself. I'm running Pop OS and I think that it's because the linux-image I need with all the debug symbols doesn't exist.
The script says I need to install linux-headers-$(uname -r) linux-image-$(uname -r)-dbg
For me, this turns into linux-headers-5.11.0-7620-generic linux-image-5.11.0-7620-generic-dbg
linux-headers-5.11.0-7620-generic exists and I'm able to download it using apt-get.
linux-image-5.11.0-7620-generic-dbg can't be installed using apt-get. I can install
linux-image-5.11.0-7620-generic, but that's not the same thing. I've spent time looking online for it and adding different keys to apt-get, but I haven't been able to find anything with that name. If the problem is not having the correct linux-image package installed, I need help being pointed in the right direction as to where I can get it.
I tried following the directions here, and I've also searched this to no avail. I tried downloading and installing linux-image-4.4.0-142-generic-dbgsym_4.4.0-142.168_amd64.ddeb but that also didn't work.
If this isn't the problem, I've provided the output of the script. Any help is appreciated.

Tip: /usr/share/doc/systemtap/README.Debian should help you get started.
Yes, debuginfo downloading has been a pain on many distros. However, if you're running Debian kernels, see: https://wiki.debian.org/Debuginfod for instructions on using a new automated system. Generally: https://sourceware.org/elfutils/Debuginfod.html .

Terminal process get killed with code ELIFECYCLE errno: 137 when VS Code is open. Quitting VS Code resolves the issue?

I've only recently in the last two days begun encountering this issue.
When I attempt to build my Angular project, It's getting to this one point and failing with errors below.
The only way I can get it to run is to quit VS code and rerun the exact same command and it builds without issue.
Any ideas what may be causing this?
137 is 128 + 9. In some situations—and I'm guessing that this is one of them—this indicates that the process died with a signal 9. Signal 9 is, on macOS (and multiple other OSes), SIGKILL. This signal is sent by the "out of memory" killer.
This also explains why exiting VSCode fixes things: VSCode is a memory hog. Exiting it returns the memory to the system.
To fix this more permanently, either reduce the memory needs of your build and/or of VSCode, or add more memory to your system.

XOpenDisplay(NULL) fails to connect to X

I was given a fairly large program to compile and run with extremely vague instructions on how to properly configure my system and install the program. I was told to use a Windows, install Cygwin, navigate to the program's base directory, and type "make". I installed Cygwin on a 64-bit Windows 7 in C:\cygwin64 as the main user (I also installed all of the default packages, plus a few extras) and then ran the makefile included with the program (this worked with no problems). When trying to run the executable with a required file argument, I was simply given the error message "cannot connect to X server." Upon examination of the code, it appears that this error was caused by a line setting display=XOpenDisplay(NULL) and then exiting when this resulted in display == NULL. Earlier, "display" had been declared as a variable of type Display. Is there any way I can get the program to connect to the X server? I have been assured that the installation of the program is extremely easy, but I'm not so sure... Thanks in advance.

Running tests in IntelliJ: cannot create JVM

I am running IntelliJ version 13.1.3, on a 32 bit windows machine.
The JVM version is 1.7.
When running even simple tests, the following error is thrown:
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Invalid maximum heap size: -Xmx4g
The specified size exceeds the maximum representable size.
Process finished with exit code 1
Can anyone assist?
Thanks
Pycharm that stands on the intellij has the jvm configuration file with this name:
pycharm.exe.vmoptions
Maybe you can find similar file in the binary path of intellij to change the jvm heap properties.
Comment from Engineer Dollery is correct. I found this in my POM file. I just commented out and the then I was able to run the test.
<!--<argLine>-Xms128m -Xmx4096m -XX:MaxPermSize=128m</argLine>-->
Go to file.
Select Project Structure.
Choose Project Settings then Select Project
There You can see Project language level
Just put it back to 8.
Project language level is changed in new update of InteliJ update thats why This error Occurs
Now just try to run your Code.
