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
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.
