Leonardo Uribe commented on MYFACES-3510: ----------------------------------------- No, it is not a bug. There is no other way to detect tomcat different to check if such class exists on the classpath. Instead, what do you need is implement a LifecycleProvider2 for glassfish or a custom LifecycleProviderFactory, to skip TomcatAnnotationLifecycleProvider.isAvailable. Unfortunately, since glassfish is CDDL/GPL licensed, we can't include that integration code in MyFaces. See: https://cwiki.apache.org/confluence/display/MYFACES/Integration+with+application+and+web+servers for more details. It could be good to share your findings later in a blog, other users have reported problems setting up myfaces with glassfish, and maybe that could help > Application components classloader memory leak > ---------------------------------------------- > > Key: MYFACES-3510 > URL: https://issues.apache.org/jira/browse/MYFACES-3510 > Project: MyFaces Core > Issue Type: Bug > Components: General > Affects Versions: 2.1.6 > Environment: WIndows Glassfish Embedded > Reporter: Ruben Martin Pozo > Assignee: Leonardo Uribe > Fix For: 2.0.13, 2.1.7 > > Attachments: MYFACES-3510-1.patch, MYFACES-3510-2.patch, > screenshot-1.jpg > > > We've seen an application classloader memory leak due to the new class > javax.faces.component._PropertyDescriptorHolder class introduced in version > 2.1.6 > This class holds a reference to a Method of a component loaded by the > application classloader.
