Answer 1

For the record (and Google), this looks like both these bugs, which were fixed in the 1.6u22 release of sun's jdk. So, first thing to do is update your JVM. If it still happens, and always happens on a particular method, you can exclude that method from compilation (as long as you're aware of the performance implications of that) with the following jvm flag:

-XX:CompileCommand=exclude,org/apache/velocity/runtime/directive/Foreach,render

(as suggested here). But, first update your jvm.
