Jukka Zitting updated COMPRESS-191:
-----------------------------------

    Description: The relaxed tar detection logic added in COMPRESS-117 unfortunately \
matches also some non-tar files like a [test AIFF \
file|https://svn.apache.org/repos/asf/tika/trunk/tika-parsers/src/test/resources/test-documents/testAIFF.aif] \
that Apache Tika uses. It would be good to improve the detection heuristics to still \
match files like the one in COMPRESS-117 but avoid false positives like the AIFF file \
in Tika.  (was: The relaxed tar detection logic added in COMPRESS-177 unfortunately \
