Apache Commons Compress 1.12 发布了，更新如下：
修复 Bug:
o SevenZFile.read() throws an IllegalStateException for empty entries.
Issue: COMPRESS-348.
o TarArchiveInputStream failed to parse PAX headers that included
blank lines.
Issue: COMPRESS-355. Thanks to Jeremy Gustie.
o TarArchiveInputStream failed to parse PAX headers whose tar
entry name ended with a slash.
Issue: COMPRESS-356. Thanks to Jeremy Gustie.
更新：
o Update requirement from Java 5 to 6.
Issue: COMPRESS-349.
o TarArchiveEntry wastefully allocates empty arrays.
Issue: COMPRESS-350.
o Javadoc for BZip2CompressorInputStream(InputStream, boolean)
should refer to IOEx, not NPE.
Issue: COMPRESS-353.
o PureJavaCrc32C in the snappy package is now final so it is now
safe to call a virtual method inside the constructor.
Issue: COMPRESS-354.
o ZipArchiveInputStream and CpioArchiveInputStream could throw
exceptions who's messages contained potentially corrupt entry names
read from a broken archive. They will now sanitize the names by
replacing unprintable characters and restricting the length to 255
characters.
Issue: COMPRESS-351.
o BZip2CompressorOutputStream no longer tries to finish the output
stream in finalize. This is a breaking change for code that relied
on the finalizer.
Issue: COMPRESS-357.oad_compress.cgi
