Hi,

When I try to debug the Designer in Eclipse per the Developer’s Guide I get the following error which repeats indefinitely. I tried cleaning/rebuilding in Eclipse and clearing the jnlp cache, but no luck. Any idea what might cause a version mismatch in initI18N? I’m using the 7.7.2 release and java 1.8.0\_11
