I will fix this in https://jira.jboss.org/jira/browse/JBPM-2844 JBPM-2844. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538607#538607] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-dev-forums] [JBoss Microcontainer Development] - JBoss Reflect Performance Javassist vs Introspection

Flavia, is there a way to get the real ClassPoolFactory to kick in earlier? The correct classpool factory kicks in just allright in the JBoss AOP integration. What exactly is being performed before the correct ClassPool Factory is set up? Taking a look at your implementation, I see that you created in jboss-kernel a ClassPoolFactoryImpl with support to installation and uninstallation of ClassLoaders. By doing this, as far as I can tell, you created a mechanism that is already present in the integration (take a look at the usage of RegisterModuleCallback in aop.xml). I mean, with things set up the way they are, I thought we had all that we needed to use JBoss Reflection over Javassist with the new pools: - there is a part that is in aop.xml that concerns ClassPools. I thought of moving this stuff to a new separate file when we integrated JBoss Reflection + Javassist with MC (mainly RegisterModuleCallback stuff) - in JBoss Reflection, there is a RepositoryClassPoolFactory class, which is the classpoolfactory intended for usage with jboss-classpool. You only need to set it as the classpoolfactory in JavassistTypeInfoFactory and set org.jboss.classpool.spi.ClassPoolRepository as the repository in RepositoryClassPoolFactory: RepositoryClassPoolFactory cpFactory = new RepositoryClassPoolFactory(ClassPoolRepository.getInstance()); JavassistTypeInfoFactory.setClassPoolFactory(cpFactory); I thought this would also be configured in this xml file that would contain stuff extracted from aop.xml So, why do you need ClassPoolFactoryImpl? If you need it for integration, maybe we should get rid of RepositoryClassPoolFactory and put it in its place instead, as RepositoryClassPoolFactory would become useless. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538584#538584] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Kabir Khan [http://community.jboss.org/people/kabir.khan%40jboss.com] replied to the discussion "JBoss Reflect Performance Javassist vs Introspection" To view the discussion, visit: http://community.jboss.org/message/538568#538568 -------------------------------------------------------------- I've written an in-AS benchmark which I'll run tomorrow to gather some more information about overheads of creating ClassInfos, looking up methods etc. What I had time to look at so far shows the Javassist implementation to be ~50x slower at obtaining the ClassInfos that the reflect one. In the meantime, looking into why the BeanMetaData classes don't appear in the statistics, I found this: protected TypeInfo get(String name, ClassLoader cl, Class<?> clazz) throws ClassNotFoundException { if (name == null) throw new IllegalArgumentException("Null name"); if (cl == null) throw new IllegalArgumentException("Null classloader"); try { CtClass ctClass = poolFactory.getPoolForLoader(cl).get(name); return get(ctClass, clazz, cl); } catch(NotFoundException nfe) { return delegateToIntrospectionImplementation(cl, name); //End up here for a lot of the bootstrap classes } } The above code was written to handle gets for generated proxy classes which will not appear in a classpool. As we know, creating Exceptions is very expensive, and could be at least part of the reason why the javassist implementation. The problem seems to be that in the bootstrap DefaultClassPoolFactory is used until it gets replaced by the real one. Flavia, is there a way to get the real ClassPoolFactory to kick in earlier? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538568#538568] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
