Build fails on Windows in cmp module due to org.codehaus.mojo:javacc-maven-plugin:2.3-jboss-1

Build of current master fails on Windows in cmp module with:

[ERROR] Failed to execute goal org.codehaus.mojo:javacc-maven-plugin:2.3-jboss-1:jjtree (jjtree-jbossql) on project jboss-as-cmp: Execution jjtree-jbossql of goal org.codehaus.mojo:javacc-maven-plugin:2.3-jboss-1:jjtree failed: basedir C:\development\git-root\jboss-as7\cmp\C:\development\git-root\jboss-as7\cmp\src\main\jjtree does not exist -> [Help 1]

Looks like a bug (or misconfiguration) in org.codehaus.mojo:javacc-maven-plugin:2.3-jboss-1 - wrong source path generation.

AS 7.1.0.Alpha1 builds fine.
