This problem is also there for a GUI application when it
encounters an exception (as GCJ spawns addr2line and c++filt).

I'm not 100% sure, but quite possibly, modifying the
CreateProcess( ) call in java/lang/natWin32Process.cc
like the following should help:
 if (CreateProcess (NULL,
 cmdLine,
 NULL,
 NULL,
 1,
- 0,
+ CREATE_NO_WINDOW,
 env,
 wdir,
 &si,
 &pi) == 0)
However, it seems that this would not work on Win9x/ME
and for 16-bit MSDOS apps (according to MSDN).
