should be easy to add as its just an interface. String
and StringBuffer implement it in JDK 1.4, so we should
patch them, too.

These methods are not part of the java 1.4 API. Why
are they needed?

It's LGPLd so we could put it in kaffe like kjc.

thanks for your java.regex implementation. I'll take a

that classpath is using gnu.regexp as the basis for
their regex implementation, too.
