I'm getting a lot of "Too many open files" errors in my JSF
application that I am writing. I want to make sure it is not my
HtmlRoundedDiv component that is in the sandbox.
I would appreciate it if a couple of developers with AWT and Image
experience could do a code review of my code for these components and
see if they see any cause for file handle leaks.
It may not be this component, but I would like to make sure.
My environment (the major components):
Tomcat 6
Java runtime 1.6.0-b105 for linux
MyFaces 1.1.5
Tomahawk and sandbox 1.1.7-SNAPSHOT
Facelets 1.1.12
Seam 1.2.1
Trinidad 1.0.3-SNAPSHOT
Example exception (although this may very well be a result of a bug,
instead of the cause of the bug):
javax.imageio.IIOException: Can't create output stream!
