It sounds like you might be doing this incorrectly. You need to place
and event into the Tcl event queue. If you just call interp.eval() it
will screw things up.

The interp is running inside another thread.

Try looking at the new docs for Tcl/Java 1.2. If they do not clear
things up then perhaps the docs need a rewrite to make the java::bind
info more clear. You might also want to check out the online version
of my Tcl/Java paper. It talks about event issues in detail. See
http://www.cs.umn.edu/~dejong/tcl/paper.html (or paper.ps).
