>>> hex(26472)
'0x6768'

You're probably looking at either an encrypted class or some random zip entry filled with nonsensical bytes located somewhere in the libraries you are loading (or some other fluke that does not really come to my mind at the moment -- perhaps someone else can weigh in?). I'd suggest trying to find the offending library via elimination.

If you use newest deobfuscator jar, it should not fail and tell you what exactly it couldn't read
