I followed the "how to reproduce" instructions and no, that does not happen. Start with a clean user directory (you can use --userdir on command line and point it to a not yet existing directory), don't use an existing project or at least provide it. From that give exact instructions to reach the point you are observing.

please attach the log file (but restart NB first)

the log file is from a debugging session when a breakpoint opened another tab?

[edrobal]

The main class is in a project and breakpoint is in an other project class (my framework).
Framework contains 440 classes.

Main class for test is in Cafi.java. Breakpoint is in MajFrame.java

ok. well I am not sure how this could happen.

the debugger has two modes (its a checkbox in the settings). One will keep opening new tabs (if they aren't open already) each time a breakpoint is hit or you step into a method, the other will open one tab and reuse that (that is the default).

I am not sure how it could duplicate an already opened tab.

You could try to reset the UI via Window -> Reset Windows, this might help in case there is something wrong with the TopComponent tracking.

New test .

• I close tab with breakpoint.
• I restart debug.
• When debugger reach breakpoint, it open new tab without showing breakpoint. (see image).

I found that if breakpoint is in same project that main class, no problem occurs.

I show you a capture before starting and after reaching breakpoint.
