Local fix

Problem summary

  • The java.net.URLDecoder has poor performance in IBM JDK
    1.4.2.The poor performance is because an internal temporary
    buffer is created without respect to the estimated size of the
    decoded string and is continuously reallocated.
    

Problem conclusion

  • This problem is resolved by initialising the buffer according to
    decoded string size and avoiding byte array reallocation every
    time. This issue is covered by Sun bug fix 4822370.
    
    The fix will be available in 1.4.2 SR13 FP4
