[Bug xml/23910] XML validation causes StackOverflowError

There have been drastic changes in XML handling, and the situation of this
bug seems to be changing.

I am a Kaffe user and the recent changes around XML handling has not
been imported to Kaffe yet.  But after manually copying GNU Classpath
sources to Kaffe, I have got the following result instead of the
StackOverflowError.

java.util.regex.PatternSyntaxException: At position 13 in regular expression
pattern:
repeated token may be empty

I think this bug should be closed now, and a new bug about the
java.util.regex.PatternSyntaxException should be filed instead.
