[rules-users] Drools Classloader Leak?

Hello, I noticed (using JConsole) that my application keeps loading more and more classes. I have over 105K classes loaded! I did a lot of debugging and isolation until I found the line that brings the number of classes loaded from 20K to 105K. It is this line: this.knowledgeBase.addKnowledgePackages(packages); packages is an array list of 8 DRLs that are compiled successfully. I am calling the line above exactly 99 times. However, I do have 99 instances of this.knowledgeBase. So, I have a total of 99 instances of "knowledgeBase", and each instance is called once (line above) with 8 successfully compiled DRLs. I am starting to think that each instance of a KnowledgeBase somehow uses its own Classloader? Do I need to manually get the current application Classloader and pass it on to each instance of KnowledgeBase to ensure that no classes are loaded more than once? Is this a leak in the Classloader that comes inside the KnowledgeBase.addKnowledgePackage method? I did post somewhere else about delays on the line above, and no wonder it sometimes takes a couple of seconds to execute that line (the largest rules file I have is 150 KB with no more than 100 rules) if it creates a new Classloader and loads the same loaded classes AGAIN. Any insights on this? P.S. I did a search on the forum and couldn't find anything related to this. If you have better searching skills and found a post in that regards, please kindly point me to it. This is a very important issue as we are going to a live production environment in 3 weeks and I am not too happy with the performance, specifically around the line above. Thank you, and have a great weekend. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Drools-Classloader-Le...
