PropertyNotFoundException while processExecution in clustered environment

Hi,

we are having some problems running our software in a clustered environment. we are using a Weblogic AS 12.1.2.0 cluster with 2 nodes.

Our application runs perfectly in a single-node-environment, but when we activate the second node we keep getting PropertyNotFoundExceptions on the second one, because the engine could not find our spring beans any more. After shutting both nodes down and starting the "faulty" one, everything works perfectly again on this node.

Node 1 down, Node 2 up -> Node 2 works
Node 1 up, Node 2 up -> Node 1 faults, Node 2 works
shut down both nodes...
Node 1 up, Node 2 down -> Node 1 works
Node 1 up, Node 2 up -> Node 1 works, Node 2 faults

This flip-flopping behavior is reproducible. We suspect, that a context switch is required but not executed. We also looked at the code in question: ProcessApplicationContextUtil.requiresContextSwitch() What if, if 2 applications on two different nodes with the same name are acessing the shared engine? Does it require a context switch?

Kind regards,

Jürgen
