> Opening and closing a large number of bzip2-compressed input streams causes
> the process to be killed on OutOfMemory when using the native bzip2 library.
> Our initial analysis suggests that this can be caused by
> {{DecompressorStream}} overriding the {{close()}} method, and therefore
> skipping the line from its parent:
> {{CodecPool.returnDecompressor(trackedDecompressor)}}. When the decompressor
> object is a {{Bzip2Decompressor}}, its native {{end()}} method is never
> called, and the allocated memory isn't freed.
> If this analysis is correct, the simplest way to fix this bug would be to
> replace {{in.close()}} with {{super.close()}} in {{DecompressorStream}}.
