This does not crash for me under jconsole.
This does crash for me under jqt.
This also crashes for me under jhs.
Here's the message I get in jconsole from jhs:
/Users/rauldmiller/Applications/j903/bin/jhs.command: line 2: 36569
Segmentation fault: 11 "`dirname "$0"`/jconsole"
~addons/ide/jhs/core.ijs -js " init_jhs_'' "
Here's the stack trace I get from jqt:
