[Solved]-Using the Eclipse remote debugger throws com.sun.jdi.InternalException-eclipse

I am not sure but I have got this plenty of times. It comes when I debug the application, and I think it occurs when the debugger tries to wrap a exception which arises due to code. At one instance while debugging when I see the logs I get some business exception, but while debugging it gave me com.sun.jdi.internalexception.

Yes I do remote debugging the servers JVM so it could also be beacuse the debugger isn't correctly connecting to the remote version as you pointed out

Just to be sure: are you remote debugging some instrumented code ?

Because there seem to be some problems with JProfiler...

Work-around: Uncheck this box:

If you have the "Logical Structures" turned on in the Expressions tab while debugging, this seems to still cause issues even in Eclipse IDE version 4.11.0. Turning it off helped me. It is not a "solution" per se rather a work-a-around.

See the Eclipse Bug 48815

I have also faced with same issue on local server. But, it was the issue of for loop. I was using:

for(Object obj: list)
{
    for(Object obj2 : list)
    {}
}

When I replaced that code by simple for loop (index based), it resolved the above issue. I think for each loop not able to iterate another list of same Type in same loop. Work around for this is replace that for loop to index based for loop.

It looks like the problem is related to the new debug feature "Show method result after a step operation": See the thread Eclipse Oxygen - Debugging Issue on the Eclipse forum:

The workaround is to go to Preferences -> Java -> Debug and disable the option "Show method result after a step operation (if supported by the VM; may be slow)".
