Is this the right place?
I am a Java programmer. I write code that works beautifully on Intel HW running RHEL 5. When I move the same code to IBM System Z Linux s390 it doesn't work. There is an enormous community of people using the Sun/Oracle JVM so it's dirt simple to get help. Google searches yield useful results.
I can't find any decent size community of people that use J9. Where do I go? Is this the right place? Who else is using these computers? Are there just a handful of them in the World?
My current problem has to do with making SSL connections from within a Java app to another server. Some security update that the admins installed broke the functionality.
My code works on Intel RHEL 5 systems using the Sun/Oracle JVM when I supply this option:
What's the equivalent option I need for the J9 JVM?
