Well, there's the famous "Java is not type-safe"
<http://matrix.research.att.com/vj/bug.html> but AFAIK that was fixed
by loading constraints
<http://www.developer.com/java/other/article.php/10936_2248831_2>

More stuff at "Type safety in the JVM: some problems in Java 2 SDK 1.2
and proposed solutions"
<http://www.kestrel.edu/HTML/projects/java/ccpe01.pdf>

AFAIK these are now fixed...
