Re: [infinispan-dev] ISPN-1374 and ModuleProperties, static collections and class loading

Hi, I'm not suggesting that the classloader is completely ignored; it is indeed evaluated at the first invocation but then if the following method is invoked again with a different classloader as argument, it will return the previously cached value: https://github.com/infinispan/infinispan/blob/master/core/src/main/java/o... Note that the method you pointed to is private, and is actually a helper for the public methods, which does cache all of it's results in static fields. So assuming this will be invoked by a single classloader only, indeed there are no issues. But is that really the case? Wasn't the purpose of the classloader parameter to load extensions from a deployed application? If so, it seems I can't deploy two different applications both attempting to start an Infinispan cachemanager. For example, I suspect that you won't be able to deploy an Hibernate Search application (or Infinispan Query) and then deploy a Hibernate OGM based application in the same container. But this is not proven as I didn't try it out, so maybe my assumptions about what the goal of this classloader parameter are wrong. So I think that, iff we need to cache this information, it shouldn't be cached in a static field, as discussed as well on https://issues.jboss.org/browse/ISPN-1190 Cheers, Sanne On 12 September 2011 19:10, Manik Surtani <msurtani(a)redhat.com&gt; wrote:
