Re: Unable to use Resouce value with $

You are right. I looked into the wrong properties in the debugger ;-)

The relevant code fragment is:

https://github.com/apache/tomee/blob/main/container/openejb-core/src/main/java/org/apache/openejb/assembler/classic/util/ServiceInfos.java#L176

It seems, that we didn't implement an escape mechanismn, so it tries to
resolve a service for $ in any case resulting in the NULL value.
