Galder Zamarreño commented on ISPN-9426:
----------------------------------------
At the protocol level, a null return is sent as an empty byte[]. The java client
transforms that into null. I guess that's cos there's no transformation to String?
If the user wanted it as text plain String it should be converted to empty String.
Debugging the code the request mediat type is String, so {testLocalTypedExecNullReturn}
should be expecting empty String instead of null? Then executing the same script
distributed should return a collection of empty Strings. [~gustavonalle] ?
Distributed script execution returning null results in
NullPointerException
