excerpt of jdb session showing the blocking thread

When doing GDB hardware debugging with Eclipse Juno/CDT 8.1.2 with arm-none-eabi-gdb, the following causes Eclipse to lock up:
1. Start hardware debuggung
2. make the target stop by breakpoint
3. Press "Show Source" in Disassembly View
When doing this on the cmdline, everything works fine, so its not gdb.
I made a quick inspection with jdb and think i found the blocking thread, see attached jdb excerpt.
Curiously, when i interrupt this thread and let all resume, Eclipse becomes responsive again and even displays the source in the disassembly view. I may then step through, and everything works as normal.
But when i restart the debug session, Eclipse does lock up for the same reason and can be unlocked again.
Normal C++ debugging does not show this behaviour.
