Summary

Change specification of javax.script.ScriptEngineFactory.getMethodCallSyntax to throw NullPointerException for null arguments.

Problem

Class: javax.script.ScriptEngineFactory Method: public String getMethodCallSyntax(String obj, String m, String... args);

This method does not specify behavior on null arguments (null for obj, null for m, null for args or any of the elements of args).

Solution

javadoc comment will be modified to explicitly state that NullPointerException is thrown for any null argument.
