So the memory is used for something useful? That is not a "memory leak". It is just a web application requiring a lot of memory. WebappClassLoader is the classloader that is used to load the classes of your webapp. Of course, it remembers every class that it loaded (to satisfy repeated class.forName() calls) and every class that it loads has a reference it it (via getClass().getClassLoader()). There may be many classes, but I do not think that the classloader itself is responsible for 300 Mb of memory. > and the data that is in the entries of the gigantic Map is > org.hibernate.impl.SessionFactoryObjectFactory > That would be a hibernate question. I have no clue what that class is about.
