[Bug classpath/26221] New: regex lookbehind not supported?

[andy dot seaborne at hp dot com]

GNU classpath from ikvm 0.24.0.1

A regular expression with a zero-width positive lookbehind does not compile:

        Pattern x = Pattern.compile("(?<=X)") ;

It seems that lookbehind isn't supported by the regex implementation.

Similarly, zero-width negative lookbehind "(?<!X)"
