Humm, this is very odd. The interp pointer being passed via JNI seems to be NULL
somehow. I don't see how that could happen. I looked back at the mailing list
archive and the only other person to report a problem like this was also running
Fedora, so that makes me think this problem may have something to do with the
Java impl on that platform. First off, could you run the Tcl regression tests?
In the directory where you build Tcl, run "make test" and see if that passes the
tests.

If everything looks ok from the Tcl side, then could you try the attached patch?
Just apply it from the root of your Tcl Blend install and then rebuild? I don't see
how these extra asserts could be triggered, it is just an extra sanity check. If you
could also add -DTCLBLEND_DEBUG to the CFLAGS def in the generated Makefile
and then run `make shell` along with "package require java" in the Tcl shell, that
would really be helpful. You can just post the output written to the shell here.
