Description

BlockDecompressorStream#decompress() return -1 in case of BlockMissingException. Application which is using BlockDecompressorStream may think file is empty and proceed further. But actually read operation should fail.

// Get original data size
try {
   originalBlockSize = rawReadInt();
} catch (IOException ioe) {
   return -1;
}
