Description
The class MissingMethodException throws an NullPointerException on getMessage() if arguments are null.
This can happen, if the someone calls GroovyScriptEngineImpl.getInterface and invokes a method without arguments on that interface. And the method is not defined in the groovy script.
The InvocationHandler calls the method invokeImpl with null as arguments, because the interface method has no arguments. If the Method is not defined in the groovy script. A MissingMethodException is thrown and catched. Than the following NoSuchMethodException(var5.getMessage()); is thrown. But getMessage() itself throws an NPE due to arguments is null.
From the Java Documentation InvocationHandler
args - an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as java.lang.Integer or java.lang.Boolean.
