When the native zlib is loaded the codec creates a > CompressorOutputStream that doesn't have the problem, otherwise, the > GZipCodec uses GZIPOutputStream which is extended to provide the resetState > method. Since IBM JDK 6 SR9 FP2 including the current JDK 6 SR10, > GZIPOutputStream#finish will release the underlying deflater, which causes > NPE upon reset. This seems to be an IBM JDK quirk as Sun JDK and OpenJDK > doesn't have this issue. -- This message is automatically generated by JIRA.
