IntelliJ debugging: Suspend whole VM then step on single thread

6
votes

I am debugging an application with lots of threads. My breakpoints are set to suspend the whole VM.

When a thread hits one of the breakpoints, I then want to use Step Over. But this appears to resume the whole VM, until that step completes.

It'd really help if I could step just the single thread that hit the breakpoint.

Is there any way to do this in IntelliJ 11.1 / Java 6? (Hope I'm not missing something obvious...)

This feature was added in IntelliJ 16 (the issue CrazyCoder referenced in his answer was resolved)

NetBeans can resume individual threads. While in debug mode, you can resume a thread from the left thread list by pressing a small button shaped like Play (►) near the thread.

Currently there's no such possibility because it may lead to deadlocks. You may vote for IDEA-43728 though.
