We have a legacy system that runs on Coldfusion 6.1 with JVM 1.6.0 build 24. It appears that TLSv 1.1 was added in build 111. Is it possible to get Coldfusion 6.1 to work with that build (or higher) and what would I have to do?
TLS 1.1 is only supported in Java 1.8 on CF10 (Oddly 1.7 and above in CF11)
I dont think CF 6.1 will work properly on higher versions of JDK. You may want to try to upgrade it to 1.8 to see if that helps.

We have a product that is running fine with JBoss 4.2.2/java 7.
We are now moving to JDK 11. simply added java 11 in the classpath and tried starting the server.
Encountered below error
OpenJDK 64-Bit Server VM warning: Ignoring option MaxPermSize; support was removed in 8.0
-Djava.endorsed.dirs=C:\PathBuilder\GE\EMEA\vp\jboss\lib\endorsed is not supported. Endorsed standards and standalone APIs in modular form
will be supported via the concept of upgradeable modules.
removed below configurations from run.bat and started the server again
-XX:MaxPermSize=128m
"-Djava.endorsed.dirs=%JBOSS_ENDORSED_DIRS%"
now getting below error and which is
interrupting the ear deployment Caused by:
java.lang.ClassNotFoundException: No ClassLoaders found for:
org.omg.CORBA.Object
Is Java 4.2.2 compatible with JDK 11 or we need to update JBoss to 7.2 or latest versions?
can someone help with this or provide related links?
JBoss 4.2 is a very old and outdated version and it only tested with JDK 1.5 and 1.6 version. If you are upgrading your JDK to 11 then you should update the JBoss to 7.3 version which is the latest available GA release from Red Hat.
You can download the jdk files of older versions like jdk6 and then replace JAVA path in the jboss run file from "set JAVA=%JAVA_HOME%\bin\java" to
"set JAVA=C:\Users\jdk1.6.0_45\bin\java"
Of course it's better to upgrade to a higher JBoss version... But in case that's not possible, you can avoid the ClassNotFoundException for org.omg.CORBA.Object by placing rt.jar from Java 8 in your JBoss-libs folder.
With this configuration you can run older JBoss versions with Java 11.
I am currently involved in a project, that requires migration of 3.5 to 4.x, 4.14 is working fine. I am raising this question because, mule 2 is supporting Java 11, while mule recommended approach is to work on adoptopenjdk 8.0
https://docs.mulesoft.com/release-notes/mule-runtime/mule-4.2.0-release-notes
It is not clear exactly what is the question, however migrating from Mule 4.1.x to 4.2.x doesn't require usually changes to applications. You are free to use Java 8 or 11, though 8 is recommended.
You can upgrade from 4.1 to 4.2 without changing the code or the java version.
So the best approach to migrate would be to use the same configuration as in 4.1
Furthermore, it's a good practice to upgrade the connectors versions of your app.
We are planning on using JDK 1.8 for Mule 3.7 CE.
In the past we edited wrapper.conf to tweak the memory JDK 1.6/1.7 uses. We did this by editing:
wrapper.java.initmemory=256m
wrapper.java.maxmemory=512
wrapper.java.additional.7=-XX:PermSize=256m
wrapper.java.additional.8=-XX:MaxPermSize=512m
Looking into the processes that are running in linux we see that Mule still uses xmx settings. If not mistaken, this no longer works in java 1.8 because it has been removed. Instead JDK 1.8 uses metaspace.
Now my question is, how/where to we make memory tweaks for Mule 3.7 using JDK 1.8? Or does Mule 3.7 CE not support this yet?
Do we simply add to wrapper.conf the following settings?:
wrapper.java.additional.16=-XX:MetaspaceSize=100M
wrapper.java.additional.17=-XX:MaxMetaspaceSize=2024m
And remove:
wrapper.java.initmemory=1024
wrapper.java.maxmemory=1024
Or we do still use the following settings?
wrapper.java.initmemory
wrapper.java.maxmemory?
Thanks!
You can keep using the initmemory and maxmemory.
Changing to Java 1.8 doesn't impact this.
We use Java 1.8 with Mule 3.7 in Linux and we are able to successfully control the heap allocation with the current setting of initmemory and maxmemory.
You might want to use Metaspace configuration only to replace PermGen settings.
wrapper.java.additional.16=-XX:MetaspaceSize=100M
wrapper.java.additional.17=-XX:MaxMetaspaceSize=2024m

Hope this helps.
I am trying to run my pharo2.0 application on CentoOS which was previously been installed in a mac. The original version is pharo2.0 so I need to run the same image CentoOS too, but I get an error which says this below :
/lib/libc.so.6: version `GLIBC_2.15' not found (required by xxxxx)
Should I be trying to upgrade the CentoOS and see if pharo2.0 works or port my whole application to a later version of pharo?
There is now a VM build especially for systems with an older libc version. In fact there is a build for Centos specifically (which has a slight variation in linkages from Debian), the latest version of which is permalinked here. See http://pharo.org/download#custom for more info.
Is there a way we can specify the JDK version we are running on? Specifically, I have a java app (non webapp) that has an incompatibility with 1.6.0_35 and is erroring out for me on CloudBees. The package recommends 1.6.0_27, is that possible to specify at deployment time?
you can specify the version with -Rjava_version on the command line - however, fine grained versions are not available (as we tend to update those) - it is more just 1.6, 1.7 or 1.8 lineage. I would recommend in that case -Rjava_version=1.7.
