-------------------------------------
Summary: File Descriptor leak in DefaultFaceletFactory
Key: MYFACES-4228
URL: https://issues.apache.org/jira/browse/MYFACES-4228
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.2.12
Environment: CentOS 7
Reporter: Peter Rainer
URLConnection opened in line 346 of DefaultFaceletFactory.java is never closed
{code:java}
try
{
URLConnection conn = facelet.getSource().openConnection();
long lastModified = ResourceLoaderUtils.getResourceLastModified(conn);
return lastModified == 0 || lastModified > target;
}
catch (IOException e)
{
throw new FaceletException("Error Checking Last Modified for " +
facelet.getAlias(), e);
}
{code}
While this usually isn't an issue in most production environments, because the
javax.faces.FACELETS_REFRESH_PERIOD is set either -1 or a high value, this can
cause unexpected side effects in both test and hot-deploy production
environments.
The result of this issue is that every time the lastModified for a composite
component is checked, the composite component file descriptor does stay open -
on my test environment we did have 500k open file descriptors for composite
component xhtml files.
