Humm, strange indeed. Could you check that Tcl is passing its own
regression tests before moving on to Tcl Blend? In the Tcl build
dir run "make test" and then do the same thing in the thread build
dir. If lots of test fail then there may be something more basic wrong
with the Tcl build under Fedora. This is a new distro with a new
compiler so it is best to start checking the basics before looking deeper
into what is going on in Tcl Blend.

As far as the Tcl Blend error goes, it is being raised in 
Java_tcl_lang_Interp_getResult defined in javaInterp.c.
I see some test cases that generate this error, but I
don't think they are exactly the same as what is going on
here.

(from javaInterp.test)

test javaInterp-6.1 {Java_tcl_lang_Interp_getResult} {
    set i [java::new tcl.lang.Interp]
    $i dispose
     list [catch {$i getResult} msg] $msg
} {1 {java.lang.NullPointerException: Invalid interpreter.}}

Also, where did you get this j2sdk1.4.2_08 release from?
And this is a 32 bit Intel type machine you are using?
