Issues in shadow classes revealed by generated tests #361

Closed aion-shidokht closed 5 years ago

aion-shidokht commented 5 years ago

Problems revealed by the generated tests (using Randoop) for shadow classes are:

Implementation of java/lang/String#<init>([III)V is not found
equals for Double is not implemented
Integer.avm_reverse returns long instead of int

Also, StringConcatFactory, LambdaMetafactory methods could not be called from deployed tests.

aion-shidokht commented 5 years ago

Directly calling the methods in StringConcatFactory and LambdaMetafactory will not be supported since it would involve implementing a shadow version of multiple classes (MethodHandles, MethodType, Lookup, MethodHandle, CallSite).
