like to switch from jboss 3 to jboss4 but i got this Exception:
Horrible Exception: java.lang.LinkageError: loader constraint violation:
when resolving overridden method
the class loader (instance of org/jboss/mx/loading/UnifiedClassLoader3) of the current class,
and its superclass loader (instance of <bootloader>),
have different Class objects for the type org/xml/sax/SAXParseException used in the signature
The SaxParserException- class is in rt.jar from the java-Compiler.
i can' t see an other class shipped with jboss
which can introduce this conflict. I tried java 5 and java 6, there is nearly the same error.
