Mike,
Normally I'd expect this guard to avoid using the resources plugin if
the plugin isn't available. Can you tell if the first guard is false?
Perhaps you using a JVM that's a bit more eager than normal about
loading classes... Which JVM are you using?
public void start(BundleContext context) throws Exception
{
super.start(context);
if (IS_RESOURCES_BUNDLE_AVAILABLE &&
System.getProperty(" org.eclipse.emf.ecore.plugin.EcorePlugin.doNotLoadResourcesP lugin ")
== null)
{
workspaceRoot = ResourcesPlugin.getWorkspace().getRoot();
}
It was nice seeing you at EclipseCon!

Ed,
After more debugging, I think the problem is caused, in part, by the JRE. I changed from the RSA installed JRE 1.5
to IBM 1.4.2, the error goes away. Switching back to the original JRE also succeeds. Maybe the j9 cache was corrupt?
Anyway, there is still some mystery. I set the system property ...doNotLoadResourcesPlugin in the launch.ini and
the osgi console reflects that fact. But stepping through the code, it is not set in that jvm environment.
Isn't that strange? I remember there was some strangeness about the servlet bridge and how it created the
execution environments in the web container. I'll poke into that now.
And why we need the resources plugin in our environment is another issue I need to resolve.
It was good to finally meet you at EclipseCon.
Best regards,
Mike
