Description lianggt08 2012-02-21 11:58:35 UTC
The fix revision 423920  was aimed to remove an resource leak bug on the  BufferedOutputStream object "ostream " (created line 804) in the method "deployWAR" of the file "/tomcat/trunk/java/org/apache/catalina/startup/HostConfig.java" , but it is incomplete. 

There are some problems: 
1. when "ostream" is not created successfully but the  temp FileOutputStream object  is created successfully  , the temp  FileOutputStream  object  will be  leaked. 

The best way to close such resource objects is putting such close operations for each object in the finaly block of a try-catch-finally structure.

r423920 had nothing to do with attempting to fix a resource leak.

The only failures that might occur during the constructor of BufferedOutputStream are the sort that signify far bigger problems that a resource leak.

Yet another bug with an over-stated severity that should be an enhancement request to clean-up the code.
