IllegalArgumentException in OpcodeStack.constantToInt about spotbugs

[jsotuyod]

The issue is caused at OpcodeStackDetector.visitCode when doing OpcodeStack.getJumpInfo, during stack.resetForMethodEntry(this). There is a stack corruption. The bytecode is (redacted):

         0: ldc           #2      // String ""
         2: astore_3              // register 3 is initialized to "" (variable String c)
...
        16: iconst_0
        17: istore_3              // register 3 is overwritten with value 0 (for int i)
...
        81: iinc          3, 1    // add 1 to register 3

However, when analyzed, at the point of the iinc instruction, the empty string is still found and the error raises.

However, this does not happen to all OpcodeStackDetector implementations, only to UnreadFields and OverridingEqualsNotSymmetrical. I'm still not sure what is so special about these two.

The snippet doesn't trigger any error on master anymore, similar stack however is in #893 and I have a patch, so closing this one.
