> Decoder incorrectly parses SIB byte when SIB.base == 5 and ModR/M.mod == 0.
> It's special case when base is absent but disp32 is present.
> This bug affects JVMTI disassembler. I've met the bug using NCAI interface when disassembling native code.
> Probably this bug will not occur for JVMTI itself because JIT does not produce such instruction.
> Suggested patch fixes this issue.
