Normalization does not support invokedynamic

[fweimer]

The large switch on bytecode instructions does not list invokedynamic, and the constant type related to invokedynamic is not supported, either. This is mostly an issue for Java 8 and code containing lambdas because before this version, javac does not emit the instruction.

BCEL throws this exception for a class compiled using javac which contains a lambda:

    Exception in thread "main" org.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 18

Unfortunately, BCEL appears to be dead upstream, and there hasn't been a release with full support for JDK 7, so it is probably best to switch to ASM or your own class file parser.

This needs to be discussed a bit further. I do agree that we need add support for newer bytecode instructions.

[fweimer]

invokedynamic has the same instruction format as invokeinterface, so the only thing needed is support for the new constant pool entry types.
I have rewritten the normalization from scratch, without any external dependencies, eliminating the BCEL dependency. Adding invokedynamic support to this should be really easy.
