code: public byte[] decompress(byte[] src, int srcOff) {

docs: Convenience method which returns <code>src[srcOff:]</code>
  decompressed.
  <p><b><span style="color:red">Warning</span></b>: this method has an
  important overhead due to the fact that it needs to allocate a buffer to
  decompress into.
  
  @param src the compressed data
  @param srcOff the start offset in src
  @return the decompressed data
