Reading the stream with harmony crashes

[jmlord]

Hi,

I'm on master branch at commit "2e1fe1ee7ab Add CCITTFactory".

The harmony library crashed when opening the attached document with the PdfTextStripper: GouvQC_Texte_78p.pdf

For now, I've just reverted 8e91a5c0ac to still use OpenJDK, and commented out a few things in LosslessFactory. Works fine 'till now. Unfortunately, I was not able to find the real fix, but thought it might help you to get a more stable release if I shared it.

Here's the logcat:
