[jboss-user] [JBoss Seam] - IllegalAccessError with SUN's JVM and Seam Remoting
If you try to use Seam Remoting running it with SUN's JVM (1.5.08 and 1.5.09) you get
an IllegalAccessError in the InterfaceGenerator class.

Switching to IBM's JVM (1.5.0.3) and the problem does not happen.
Changing the lines (584~586) from (CVS-20061029):
| typeSource.append(fields);
| typeSource.append(accessors);
| typeSource.append(mutators);
|
to:
| typeSource.append(fields.toString());
| typeSource.append(accessors.toString());
| typeSource.append(mutators.toString());
|
and rebuilding SEAM solved the problem.
Not a bug directly related to SEAM but I guess most people running Windows use SUN's
JVM.
