Apache Spark is written in Scala and that runs on z/OS so I would
suggest no probs!
Scala is not for the neophyte. It's a fantastic language with so many
plus points it makes Java look ordinary. However, beneath the succinct
syntax lies
hideous complexity that the average Java programmer cannot grok let
alone your average COBOL coder. It twists the brain!

One could argue that this precludes anything not actually written in
the Java language. Or one could argue that it's Java bytecodes or
class files that are or are not eligible, in which case Scala would be
fine. But any argument that says Scala is eligible would work just as
well to argue that COBOL compiled into a Java class would be eligible;
something I expect IBM would not agree to.
Why not? One could similarly argue that HLASM code created
by the PL/S compiler is supported by HLASM, but HLASM code
created by the Dignus C compiler is not. The telling point is
whether the intermediate product conforms to the specifications
of the subsequent processor.
I suppose the bottom line, as always, is that IBM can decide to
interpret this the way it wants at the time it wants.
Sort of. If HLASM fails PL/S output, IBM is free to modify HLASM
if they deem that easier than fixing PL/S. IBM probably wouldn't
do the same for Dignus C. But Dignus might object strongly if HLASM
is violating its own published specifications.
