[jira] [Created] (TIKA-1446) CHM parser : wrong decompression of aligned blocks

Bin Hawking created TIKA-1446:
---------------------------------

             Summary: CHM parser : wrong decompression of aligned blocks
                 Key: TIKA-1446
                 URL: https://issues.apache.org/jira/browse/TIKA-1446
             Project: Tika
          Issue Type: Bug
    Affects Versions: 1.7
            Reporter: Bin Hawking
            Priority: Critical


If an embedded file contains aligned blocks, the parser outputs chaotic text or empty text as to this file.

I have fixed it myself, corrected decompressAlignedBlock() and its preparation methods. Mostly this bug is due to misusing main tree/align tree/length tree. And some tree is built wrong.
