[rules-users] ASMAccessorImpl classloader issue?

[ollem]

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!

Best Regards // Olle Mårtensson
