> File handle leak in MessageVetter
> ---------------------------------
>
> Key: DERBY-5480
> URL: https://issues.apache.org/jira/browse/DERBY-5480
> Project: Derby
> Issue Type: Bug
> Components: Build tools
> Affects Versions: 10.9.0.0
> Reporter: Knut Anders Hatlen
> Assignee: Knut Anders Hatlen
> Priority: Minor
> Attachments: d5480-1a.diff

>
> MessageVetter, which is executed by the build script, contains the following
> code to load a message file:
> properties.load(new FileInputStream(file));
> The FileInputStream isn't closed. Since MessageVetter runs embedded in the
> Ant process, file handles may be held open and cause problems later in the
> build. MessageVetter goes through more than 800 files, so the number of open
> file handles may be high when it has completed.
> Even though FileInputStream has a finalize() method that calls close(), so
> the streams will be closed eventually, we should close the streams explicitly
> to release system resources as early as possible.
