This was originally filed in GNU Classpath's BTS, but it should probably be here
as well.

We were recently having some problems with the search functionality in native
eclipse[1]. It boiled down to the lack of quoting regex constructs support in
gnu.regexp.RE (\Q, \E). A simple test:

Pattern.compile("\\Q" + "boo" + "\\E").matcher("Peekaboo").find();

returns false using classpath and true using java-sun.

I'm attaching a more comprehensive Mauve test for the java.util.regex
functionality. It consists of three test suites, adapted from PCRE[2] (which is
BSD licensed):

- testdata1: tests that are currently passed by classpath
- testdata2: tests that currently fail (disabled since they probably
need to be reviewed)
- testdata3: tests that use quoting constructs

I'm also attaching a tentative patch for the quoting constructs problem.
