Description lianggt08 2012-02-23 08:40:20 UTC
The fix revisions 270637, 272826, and 905179 were aimed to remove resource leak bugs on the Reader object "r", the Writer object "w", the BufferedWriter object "bw" in the method "doReplace"of the file "/ant/core/trunk/src/main/org/apache/tools/ant/taskdefs/optional/ReplaceRegExp.java" , but it is incomplete.

In the head revision (rev1037691), there is still some problem: 
1. the BufferedReader object "br" created at line 369 isn't closed, and  it will be leaked. 

The best way to close such resource objects is putting such close operations for all resource objects in the finaly block of a try-catch-finally structure and then putting all other code in a try block.

The problem still exists.
