Description

TestSearchArgumentImpl output has stuff like this:

Continuing ...
java.lang.NoSuchMethodException: <unbound>=GenericUDFBridge.setUdfClass(Class);
Continuing ...
java.lang.NoSuchMethodException: <unbound>=GenericUDFBridge.setUdfClass(Class);

XMLDecoder used in deserializeExpression by default would swallow some exceptions, such as the ones above; setExceptionListener can be used to receive those.
When I set the listener to inline class that would rethrow them wrapped in RuntimeException, the test failed.
Discovered in HIVE-4914.

It may be a test-specific issue, or some general Expr serialization issue that may affect the real case.
Also Kryo can now be used for serializing stuff.
