James 2.3 is unmaintained, end of life.
Feel free to reopen if work is planned on this.
> An incomplete fix for the resource leak bugs in RemoteManagerHandler.java
> -------------------------------------------------------------------------
>
> Key: JAMES-1383
> URL: https://issues.apache.org/jira/browse/JAMES-1383
> Project: James Server
> Issue Type: Bug
> Components: Remote Manager
> Affects Versions: 2.3.0, 2.3.1, 2.3.2
> Reporter: Guangtai Liang
> Priority: Critical
> Original Estimate: 10m
> Remaining Estimate: 10m
>
> The fix revision 108172 was aimed to remove resource leak bugs on the
> BufferedReader object "in" (created in line 227), the PrintWriter object "out
> " in the method "handleConnection"of the file
> "/james/server/trunk/src/java/org/apache/james/remotemanager/RemoteManagerHandler.java
> (now moved to
> /james/server/branches/v2.3/src/java/org/apache/james/remotemanager/RemoteManagerHandler.java)"
> , but it is incomplete.
> There are some problems:
> 1. when "in" isn't created successfully but the temp InputStreamReader object
> is created successfully (at line 227), the temp InputStreamReader object will
> be leaked.
> 2. when "out" isn't created successfully but the temp BufferedWriter object
> is created successfully (at line 228), the temp BufferedWriter object will be
> leaked.
> 3. when the temp BufferedWriter object isn't created successfully but the
> temp OutputStreamWriter object is created successfully (at line 228), the
> temp OutputStreamWriter object 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 in the head revision (the temp InputStreamReader
> object created at line 257 and the temp BufferedWriter object and the temp
> OutputStreamWriter object created at line 258 can be leaked). The buggy code
> is copied as bellows:
> public void handleConnection( final Socket connection )
> throws IOException {
> socket = connection;
> String remoteIP = socket.getInetAddress().getHostAddress();
> String remoteHost = socket.getInetAddress().getHostName();
> synchronized (this) {
> handlerThread = Thread.currentThread();
> }
> try {
> 257 in = new BufferedReader(new
> InputStreamReader(socket.getInputStream(), "ASCII"),
> 512);
> 258 out = new PrintWriter(new BufferedWriter(new OutputStreamWriter
> (socket.getOutputStream()), 512), false);
> ......
> } catch ( final IOException e ) {
> ......
> } finally {
> resetHandler();
> }
> }
