Hi,

after updating JRebel from 5.6.2 to 5.6.3, my application won't launch any more in Eclipse 3.8:

2014-09-12 10:30:34 JRebel: ERROR Failed to start a plugin org.zeroturnaround.javarebel.webobjects.WebObjectsPlugin in sun.misc.Launcher$AppClassLoader@43be2d65: java.lang.NullPointerException

The JRebel support suggested adding -Drebel.wo.optimize=true to the VM arguments, which works but gets me only to:

The failing code snippet is:

if (ReloaderFactory.getInstance().isReloadEnabled() && WebObjectsPlugin.isEnabled()) {
new WOJRebelSupport();
}

JRebel support answered:

This something what's throwing the errors seems bit dated, to say the least, as the plugin (3rd party contribution, to be noted) doesn't have such method.

Does anyone else have similar problems?
