Hi,

When starting the a debug session I got the following Execption with CCSV5.2beta3:

Exception in thread "pool-1-thread-1" java.util.ConcurrentModificationException
   at java.util.HashMap$HashIterator.nextEntry(Unknown Source)

   at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source)
   at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
   at java.lang.Thread.run(Unknown Source)

This indicates a programming error, where multiple threads access non-thread-safe data structure.

Please forward this report to the development team, so that they can fix this problem.

Thank you in advance, Clemens

Btw I continue to get crashes using the debugger with 5.2beta3, should I collect the hs_err files and upload them somewhere?

Hi Clemens,

for sure feel free to send us crash logs/reports. These are always good for us to have. Any .dmp files generated and error logs are good.

Would you be able to send them for this case?

Best Regards,
Lisa

A concurrent modification exception doesn't result in a crash dump, as its a fail-fast warning mechanism (but for sure such code will lead to uncertain results).

The stack-trace provided will provide enough information for the dev-team to know where to look, please forward it.
