Crash InstructionReader on somes obfuscated dex
Hi!
On somes obfuscated dex (see attach) InstructionReader is crash.
If payloads of pseudo-instructions inject between normal instructions in body.
This case is not taken in your inplementation.
But the real Dalvik VM normal process this code.
Thank you!

Possible implementation for this. Note: is works only for cases when payload-data follow after instruction-owner, else throw exception. For all cases, more modifications are required, but they are easy to implement. Sorry for the very bad English and typos. InstructionReader.zip
