Check syntactic errors in Python source string for Java PythonCallableSource object #21568
Description
We would like to have correctness checks for Python source strings when we construct PythonCallableSource object in Java SDK.
We might launch Python subprocess in PythonCallableSource.of method and call eval function to easily check syntactic correctness. Python parser module from Jython library could also be helpful.
