I still think that even if it was your fault the bug exists, they should still pay you to fix it. I mean, every bug can't be your fault it is impossible to test every possible case and it's just part of the life cycle of software. Don't stop providing support as long as they pay!

I have never enjoyed anything I have ever used with Java, the only way I can stand it now is because I bought a brand new gaming computer which doesn't crash when I run the JVM.

you should stop using it
