Product Version: NetBeans IDE Dev (Build 200805150003) Java: 1.6.0_10-beta; Java HotSpot(TM) Client VM 11.0-b11 System: Linux version 2.6.22-14-generic running on i386; UTF-8; en_US (nb) Observed: When moving line breakpoint from one group to another the exception poped. After closing the exception the breakpoints could be moved normally. when trying to reproduce it - sometimes the exception didn't occur, but the breakpoint could not be moved, sometimes everything worked fine Expected: The breakpoint should just be moved to another group Steps to reproduce:toggle few line breakpoints in some java source -> in the breakpoints view select at least two and set a group name for them by invoking "Set Group Name" from popup menu. -> set a different group name for another breakpoint -> set the group name of one of the former group to the name of the latter group
I have tried to reproduce it but I have not been successful. Could you attach the exception's stack trace, please?
Created attachment 61477 [details] stack trace
It is still hard to reproduce for me, seems to occur rarely, any additional hints how to obtain the exception with a good probability are welcomed. The problem is somewhere in nodes visualization, not necessary bug in debugger. It does not break debugger functionality and it is not visible so much => decreasing priority to P4.
It was hard to reproduce for me too - seems to occur more often if u manipulate with the breakpoint groups a lot, but still not every time.
Nothing from debugger on the stack trace.
