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
