JBOSS Error - Visual Page Editor does not work on your Eclipse Mac OSX

If you receive this error when running Visual Page Editor from JBoss tools on Eclipse  : the error is due to a missing cocoa version of XUL runner as you can see in the following stacktrace org.jboss.tools.vpe.xulrunner.XulRunnerException: Bundle org.mozilla.xulrunner.cocoa.macosx is not found.
at org.jboss.tools.vpe.xulrunner.browser.XulRunnerBrowser.getXulRunnerPath(XulRunnerBrowser.java:219)
at org.jboss.tools.vpe.xulrunner.browser.XulRunnerBrowser.initXulRunner(XulRunnerBrowser.java:114)

then most likely, you have a Eclipse installed using 64-bit. JBoss tools currently works only on 32-bit Cocoa. Details are here : https://issues.jboss.org/browse/JBIDE-4523?focusedCommentId=12496662&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel

So too bad for me, I need to use 32-bit Eclipse until such time that 64-bit is supported.
