regex match code does not handle $

           Summary: regex match code does not handle $
           Product: Ant
           Version: 1.6Alpha (nightly)
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core
        AssignedTo: dev@ant.apache.org
        ReportedBy: peter.reilly@corvil.com


Ant uses \num  to identify the matched group,
jdk14 and jakarta-oro uses $num to identify the
group. The code in ant correctly replaces the \
with $. However, it does not escape any $ on
the input.

The following 
   <replaceregex pattern="@([^@]+)@" replace="${\1}"/>
fails on jdk14 as Matcher#appendReplacement gets passed 
"${$1}" rather than "\${$1}".
