Summary: Our patch to Javalib has been accepted, so we can parse programs with invokedynamic! invokedynamic still crashes Sawja, but I have worked around this by replacing all invokedynamic's with invokestatic's before passing them to Sawja. This means we can handle everything about invokedynamic except calling the correct function (I call a dummy function with the correct signature for now). We can try to actually call the right method in the future. Reviewed By: jvillard Differential Revision: D4160384 fbshipit-source-id: a8ef4e1master
