-----------------------------------------
If I'm not mistaken, at the moment Class constants in the LHS must not be specified
with the trailing ".class"

Wolfgang Laun commented on JBRULES-2951:
----------------------------------------
Apparently you can write a comparison such as
clazz == java.lang.Object
but you cannot write
clazz == (java.lang.Object)
which is rather quirky. You can write
clazz == (java.lang.Object.class)
but not any more:
clazz == java.lang.Object.class
Headache!
Note that the JIRA title says "regression...". I have code where
clazz == (java.lang.Object.class)
is used, which - alone - is accepted by 5.3.0 (which makes it even more confusing) but
fails when combined with '||', e.g.
clazz == null || clazz == (java.lang.Object.class)
regression: cannot compile return value
"(java.lang.Object.class)"
