Julian Hyde commented on CALCITE-3175:
--------------------------------------
The current PR uses Class.forName to create a class mentioned by name in the
serialized form. This might create a security hole.
The receiver ought to know the target (enum) class already, so why store it in
the serialized form?
> Serialize to json of trim function cause exception
