[ JDK VERSION : other ] Example: Having "Local Variables", "Breakpoints", "Watches" open in "Output" tab group ... Opening of "Debugging/Sources" should recognize recent debugger-related tabs in output group, and should be located there, instead of opening new group (Issue 145210). Related: Issue 123118
it is up to a TC in what mode it opens -> reassigning. However it seems as duplicate of the issue 145210 that was closed as wontfix.
It's not a duplicate, this is about some intelligent functionality that tries to keep debugger windows together. It will be considered during 7.0 planning.
