> I've built a simple web-application, which contains one servlet loaded at start-up. In its init() method an instance of RepositoryImpl() is created, in its destroy() method this instance is stopped (using shutdown()).
> From the servlet code, only classes in jackrabbit-core, JCR API and Servlet API are referenced.
> jackrabbit-core version is 1.4.5, and jackrabbit-jcr-commons version is 1.4.2. Other jackrabbit libs are all of 1.4 version.
> Even if servlet's doGet() method never gets called, when the web-application is redeployed, all its classes still hang in memory, which produces a memory leak.
> init() method is
> public void init() throws ServletException {
> super.init();
> try {
> RepositoryConfig repoConfig = RepositoryConfig.create(getClass().getResourceAsStream("repository.xml"), ".");
> repo = RepositoryImpl.create(repoConfig);
> } catch (Exception e) {
> throw new ServletException(e);
> }
> }
> while destroy() method is
> public void destroy() {
> repo.shutdown();
> super.destroy();
> }
> Even when I applied patches from JCR-1636 and added TransientFileFactory.shutdown() call to destroy() method, nothing has changed.
> Tested this in Jetty 6.1.9 and Tomcat 6.0.14.
