What I meant to say was that a wacky ref counting problem that
I have not been able to pin down seems to be causing a core
dump inside the JVM. It happens at the exact same spot in
the test suite, but getting a small test case is really tricky.
After many hours of trimming, the minimal code that will crash
was identified as:
if 1 {
if {[string compare test [info procs test]] == 1} then {source defs}

list [catch {
set a [java::new {int[]} 5 {6 7 8 9 10}]
$a getrange 1 3
} msg] $msg
} {0 {7 8 9}}
puts "---------------- 11.8"

puts DONE!
exit
You can save it in a file or just copy and paste it into
the shell you started with "make shell". It crashes every
time on my Linux box (Red Hat 6.2) during 11.14.
I even tried it with Jiang's patch to add an additional
incrRefCount() and decrRefCount() call, but that did no good.
I am rather stumped at this point. I could do some more
debugging, but at this point I would rather punt on
the ref count issue and focus on the Notifier.
