----------------------------------------------------------
Also, all the code calling into user plugins should be doing a "catch
(Exception e)" and not catch TezException. TezException only handles the
specific exception thrown by ReflectionUtils but does not catch exceptions
thrown by the user code itself i.e. the constructor could throw a completely
different exception.
