Create a known.issues patternset in the testsuite/build.xml (for all 3 branches). Initially, this will be empty, but it will eventually contain a list of tests to exclude from the testsuite if the exclude.known.issues property is set.

<property name="exclude.known.issues" value="false">

<patternset id="known.issues.excludes">
<exclude name="org.jboss.test.something.test.TestCase" if="exclude.known.issues"/> <!-- JBAS-XXXX -->
</patternset>
...
<fileset dir="${build.classes}">
<include name="**/*UnitTestCase.class"/>
<include name="org/objectweb/jtests/**/*Test.class"/>
<patternset refid="all.excludes"/>
<exclude name="**/test/xa/test/XAUnitTestCase.class"/>
<patternset refid="known.issues.excludes"/>
</fileset>
