Tika calls > CompressorStreamFactory.createCompressorInputStream(in) to detect if the file > is a compressor stream, but CompressorStreamFactory erroneously detects it as > a LZMACompressorInputStream and when the LZMACompressorInputStream is > instanciated the OOME is thrown. This error does not happen with > commons-compress versions prior to 1.10, when auto detecting LZMA streams was > added.
