BZip2CompressorInputStream doesn't handle being given a wrong-format compressed file
------------------------------------------------------------------------------------

                 Key: COMPRESS-174
                 URL: https://issues.apache.org/jira/browse/COMPRESS-174
             Project: Commons Compress
          Issue Type: Bug
          Components: Compressors
    Affects Versions: 1.3
         Environment: Linux and Windows
            Reporter: Andrew Pavlin
            Priority: Minor


When reading a file through BZip2CompressorInputStream, and the user selects a file of the
wrong type (such as ZIP or GZIP), the read blows up with a strange ArrayIndexOutOfBoundException,
instead of reporting immediately that the input data is of the wrong format.

The Bzip2Compressor should be able to identify whether a stream is of BZip2 format or not,
and immediately reject it with a meaningful exception (example: "ProtocolException: not a
BZip2 compressed file").

Alternatively, are there functions in commons-compress that can identify the compression type
of an InputStream by inspection?

Example stack trace when using a ZIP input file:

Exception in thread "OSM Decompressor" java.lang.ArrayIndexOutOfBoundsException: 900000
