+ | Bug #: 3085 Product: Xerces-J |
+ | Status: NEW Version: 1.4.2 |
+ | Resolution: Platform: All |
+ | Severity: Normal OS/Version: All |
+ | Priority: Other Component: Core |

+ +============================================================================+
+ | DESCRIPTION |
+ In both StringPool and SymbolCache the following code pattern is used:
+ try {
+ array[index] = x;
+ }
+ catch (ArrayIndexOutOfBoundsException ex) {
+ array = makeArrayBigger(array);
+ ...
+ }
+ As it turns out throwing and catching an exception is costlier in more taxing
+ in a multi-user environment than comparing the index value to the array size.
