--- Comment #6 from Coty Sutherland <csuth...@redhat.com> --- OK, after a lot of poking around I think I found a solution :D I figured out that the problem was with a FileInputStream. Tomcat7 doesn't use FIS' in the webresources package, but tomcat8+ does. I determined this by noticing that that the file handle was hanging around (via lsof) after the MOVE call is made. Then I took a look at a heap dump taken after the issue (before a GC removed the reference) and found the FIS object in a Finalizer. After that, I started in the move method and stepped through the method with jdb while periodically running lsof to see when the handle was created. This led me to java/org/apache/catalina/servlets/WebdavServlet.java:1679 where a FIS was being retrieved from the resource, but not closed. My patch drops the FIS into a variable and then adds a close call after the write method is invoked to remove the handle. I don't think the write method should close the FIS since the FIS din't originate within the write method, which is why I put the close after the write returned. I verified that this doesn't leave a handle open on linux and that the move operation from my reproduction steps works on both linux and windows after the patch is applied.
