Differences between Regular Expressions in Java and ECMA-262 (AS, JS)

Question

I need to convert Java regular expressions to ActionScript regular expressions.

Apparently, there are no pre-converters, so I'm trying to write them myself. Is there any resource that lists all the differences?

I am aware of regular-expressions.info, but there does not seem to be an exhaustive list of differences.

thank
