Jonathan Eagles commented on HADOOP-8535:
-----------------------------------------
http://jira.codehaus.org/browse/PLXCOMP-202 is the JIRA that added the JavacCompiler classloader cache.
The build command I executed was
mvn clean install -Pdist -Dtar -DskipTests -Dmaven.javadoc.skip
which was performed with an empty .m2 cache (nexus enabled) and a clean git repo at the top level.
