Even a much serious problem is with java.util.regex  .. specifically,
this method

http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html

static Pattern compile(String regex)

The String I tested (very large string), java6 could execute the
method in few seconds. GCJ took more than one minute. It was more than
40 times slower.
