steps to reproduce:
1) get a test jre from http://jre.us.oracle.com/java/re/jdk/9-jigsaw-m2/nightly/b40_2014-11-21-1021_1764/bundles/macosx-amd64/jre-9-ea-macosx-amd64.dmg and install it
2) get a stable JDK (8u20 or above) for launching the java test below
3) get ant 1.9.3 or above
4) get the ws from http://closedjdk.us.oracle.com/jdk9/client/deploy
5) go to directory of this ws: <ws>/test/functional
6) modify "deploy.args" to make sure parameters are correct for JRE/others, but try to intend to have different values for TOMCAT_HOME and TOMCAT_HOME_MANUAL, like we have:
TOMCAT_HOME=/Users/egtc/Desktop/tomcat1
TOMCAT_HOME_MANUAL=/Users/egtc/Desktop/tomcat2
7) export JAVA_HOME to point to that stable JDK
8) export PATH to include "ant" command
9) run the following plugin suite as:
ant -f buildpluginmanual.xml liveconnect
10) java test GUI will be launched

Expection: there should be no issue to see java test GUI at step 9
Actual Results:
at step 9), you will see the following errors:

---------------------
you have to build "compile-driver" target as this liveconnect does depends on this, but somehow, no this dependency in ws.

Not sure for other suites, please double check.
