[jboss-user] [JBossCache] - memory leak

[gmeroz]

I use JBossCache-all-2.0.0.ALPHA2.

i have a memory leak in my application when i use JBossCache. The following test reproduce it. It add 100 Person object to the cache, than it remove them from the cache & and repeat...

When i use profiler, I see that the number of instances of Person is raising. (even if i force GC).


  | public void testMemoryLeak(){
  |         PojoCache cache = PojoCacheFactory.createCache("com/bevents/infra/service/cache/cache.xml", true);
  |         String category = "testCat";
  |         while (true) {
  |             for (int i=0 ;i<100; i++) {
  |                 Person person = new Person();
  |                 person.setName("aaa");
  |                 cache.attach(category+"/testPerson"+i,person);
  |                 assertEquals(person,cache.find(category+"/testPerson"+i));
  |             }
  |             // delete from the cache.
  |             cache.getCache().getRoot().removeChild(Fqn.fromString(category));
  |             assertNull(cache.find(category+"/testPerson0"));
  |             System.out.println("sleep");
  |             try {
  |                 Thread.sleep(5000);
  |             } catch (InterruptedException e) {
  |                 e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
  |             }
  |         }
  |     }
  | 

this is the configuration XML loaded for the cache:

  | <?xml version="1.0" encoding="UTF-8"?>
  | <server>
  |     <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/>
  |     <mbean code="org.jboss.cache.TreeCache"
  |         name="jboss.cache:service=TreeCache">
  | 
  |         <depends>jboss:service=Naming</depends>
  |         <depends>jboss:service=TransactionManager</depends>
  | 
  |         <attribute name="TransactionManagerLookupClass">org.jboss.cache.DummyTransactionManagerLookup</attribute>
  |         <attribute name="IsolationLevel">READ_COMMITTED</attribute>
  | 
  |         <attribute name="CacheMode">LOCAL</attribute>
  |     </mbean>
  | 
  | 
  | 
  | </server>
