public static class JmsMatsException.JmsMatsUndeclaredCheckedExceptionRaisedRuntimeException
Thrown if a undeclared checked exception propagates out of the user-supplied lambda. This should obviously
not happen, but can happen nevertheless due to checked-ness being a compilation-feature, not a JVM feature.
Groovy chooses to ignore the concept of checked exceptions - and it is also possible to throw such an Exception
with the "sneaky-throws" paradigm in pure Java (Google it) - and therefore, it is possible to get such Checked
Exceptions propagating even though the signature of a method states that is should not be possible.
Shall cause rollback.
