Sporatic OutOfMemoryErrors on bootup in a 64bit environment

For some reason, JBOSS attempts to unzip every deployment (including XML files). The code is in DeploymentInfo (See below). In a 64bit environment, when trying to unzip an xml file (jboss-service.xml), the zip library is throwing an OutOfMemory error that bypasses the exception handling logic below. The logic attempts to catch Exceptions but Not errors. A work around is to catch Throwable but one questions the needs to unjar every file including non-zips on startup. This is a bug that should be fixed. This happens on startup with the 'all' deployment.

public Manifest getManifest()
{
try
{
if (manifest == null)
{
File file = new File(localUrl.getFile());

if (file.isDirectory())

{ FileInputStream fis = new FileInputStream(new File(file, "META-INF/MANIFEST.MF")); manifest = new Manifest(fis); fis.close(); }

else // a jar
manifest = new JarFile(file).getManifest();

}

return manifest;
}
// It is ok to barf at any time in the above, means no manifest
catch (Exception ignored)

{ return null;}

=== Does Not catch OutOfMemoryError ====
}
