Re: [rules-users] ASMAccessorImpl classloader issue?

Hi! I'm trying to use jackson to deserialize JSON to declared types. When I do that I get classloading problems when inserting the fact into knowledgespace. I have explicitly set the context classloader to org.drools.rule.JavaDialectRuntimeData$PackageClassLoader during deserialization. The problem only occurs when I insert facts at a high rate. I use a http to send data that will be inserted as facts and when I send only 100 facts I have no problems, when I step this up to around 500 I get the following stacktrace. Has anybody seen anything like this? Please help me!
