This issue was originally marked as duplicate of issue 158750, that is already resolved. This issue is still valid, so this seems to be another issue, but it might be related. Build: NetBeans IDE Dev (Build 200908210201) VM: Java HotSpot(TM) Client VM, 14.2-b01, Java(TM) SE Runtime Environment, 1.6.0_16-b01 OS: Windows 7, 6.1, x86 User Comments: stefan79: Step by step - Debugging GUEST: 'Continue' while debugging rhinoguy: Pressed my HotKey (F10) to step over a breakpoint. GUEST: When I debug my multi-threaded desktop application I get this exception often when I try to do a debugging session. fzamboj: This one happened when I was stepping over method in java.awt.Container.java GUEST: (I changed debugging options) Set breakpoint before running program Hit breakpoint Step over GUEST: debugging a test file. JMS based project GUEST: Placed a breakpoint - app broke - then tried to step over line in debugger - instead of stepping over - action acted like a "continue" where the application is now running cyhelsky: on step over while debugging netbeans limo42: Hit 'Step Over' after hitting a breakpoint GUEST: debugging GUEST: ARrrrrrrggggg Can't work like this anymore tkhh: changed the Java debugging options to stop all threads at breakpoint and to resume all threads at step forward. Since then breakpoints in debugging are effectively no longer correctly working, probably due to this error occuring when pushing next step after the first breakpoint was hit. mgoe: I was trying to continue a program which has stopped at a breakpoint. bburette: Pressing F8 to step over Stacktrace: com.sun.jdi.IncompatibleThreadStateException at com.sun.tools.jdi.ThreadReferenceImpl.privateFrames(ThreadReferenceImpl.java:365) at com.sun.tools.jdi.ThreadReferenceImpl.frame(ThreadReferenceImpl.java:277) at org.netbeans.modules.debugger.jpda.jdi.ThreadReferenceWrapper.frame(ThreadReferenceWrapper.java:132) at org.netbeans.modules.debugger.jpda.actions.StepActionProvider.exec(StepActionProvider.java:364) at org.netbeans.modules.debugger.jpda.util.Operator$1.run(Operator.java:433) at java.lang.Thread.run(Thread.java:619)

It's apparent that the fix of issue #158750 was not good enough...
Moving to P3 - there are just 3 duplicates from 6.8 dev. The rest belongs to issue #158750. We will try to analyze how this can happen, any steps that leads to this error are welcomed.
