Why's that? Do you not have addr2line and c++filt in your
PATH?

My smoke tests with that GDB for Java on Win32 were
fairly successful (I used Mohan's GCJ 3.4 snapshot).
The one odd thing I noticed, and that you might be
facing as well, is that it needs help in setting
up the initial breakpoint/file-to-list.
For example:
 b HelloWorld.java:5
or
 l HelloWorld.java:1
After that, it's smooth sailing.
Chris Johns (cjohns at cybertec dot com dot au) seems to
have provided that - you might want to contact him
directly for more information/insights.
