<div class="jive-rendered-content"><p>I have just committed the rest of JBAS-8250 to trunk.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>As far as I can see, the non-flat DeploymentImpl is not causing the OutOfMemoryError. Comparing DeploymentImpl vs FlatDeployment, I had to run the deployers/weld tests the same number of times (16 times) to get a OutOfMemoryError.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Anyway, I profiled JBoss AS memory usage with those tests. A very high number of HashMap$Entry instances called my attention, and most of them couldnt' be garbage collected. JProfiler showed them as being held by org.jboss.logmanager.LogContext, so I don't think I got to any useful results.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Going back to JBAS-8250, I see 4 pending issues:</p><p>- the library scanning that Ales is working on</p><p>- we need also a mechanism to scan for libs referenced from manifest files, creating BDAs for any lib that contains META-INF/beans.xml</p><p>- a FIXME that I added to DeploymentImpl (regarding the undeployment of loaded BDAs)</p><p>- replace the slow Classpath implementation by the NoDuplicatesClasspath</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The last two are pretty simple to do. The second one concerns me most. Any ideas on how should we tackle that one?</p></div>
