Johnathan James commented on JBSEAM-4506:
-----------------------------------------
Any opinions on how to fix this?
The issue happens at line 479 of GWTService.java,
return Class.forName(serializedName, false, classLoader);
the variable serializedName is set to 'java.lang.String/2004016611'. This string is not mapped to a class, so forName() returns null, and thus the error.
One suggestion was to just chop off anything after the '/' in a given serializedName. That will work, but potentially with big side effects.
My suggestion is to add the serializedName 'java.lang.String/2004016611' to the map of classes that forName() is looking at. Alas, I don't know how to do that..
Suggestions? I'll be more than glad to submit a patch.
