# A fatal error has been detected by the Java Runtime Environment

I was just running some tests on my code. When I closed my code, this was displayed in cmd prompt (where I compile and test run my code):

Here is C:\Users\cc11rocks\Documents\JavaCrap\Pong\hs_err_pid3444.log

Was this my fault? What is going on? Was there a memory "overrun"? Were there too many threads running at once?
This looks BAD. Please help!

The help will consist of doing what the message says: report the bug to Oracle so that it gets fixed.

This is not caused by any error in Java code; these types of errors are generated by native code. That can be any 3rd party library, or the JVM itself. In this case it appears to be the latter, so a bug report seems a good step.

Thanks. I was using the Java VM. I'll send them a bug "complaint".
Thanks,
