IllegalArgumentException during analysis

[Bananeweizen]

When adding this as plugin to spotbugs, I see one new exception in our build logs.

The method signature in question looks like this:

@Override
public void format(@NonNull final URI formattedObjectUri) {

where NonNull is org.eclipse.jdt.annotations, and URI is org.eclipse.emf.common.util.URI

Anything I can additionally report to help debugging? It's unfortunately not open source.

Really interesting, it seems that your code has LDC or LDC_W but after this instruction there is no stack item in OpcodeStack. It should be impossible... I guess this problem comes from SpotBugs side.

If you cannot share the code, can you share the bytecode around program-counter 14 in this method? Or can you send .class file to me privately?
