IntelliJ debugger gets stuck

Question

I\'m debugging a normal Java application, no GUI, just a lot of computations and ~5 calls in the stack for the main thread when the problem occurs. Basically it keeps saying \"C

Answer 1

The following fixed it for me on IntelliJ 2018.2.4:

• Right click breakpoint
• Toggle the setting to suspend "Thread" instead of "All"

This won't be helpful if you actually need to suspend all the threads for debugging, but it got rid of the "Collecting data..." and "Waiting until last debugger command completes" messages for me. The setting also persists for subsequent breakpoints, so you only need to change it once.
