Greg, this is the same bug you discovered which I thought we had taken care of by changing the prefix for the resolver.

Why the cdt supplier is pulling out the JAXB resolver I don't know ...

Mike,

It looks like you are not using the version from HEAD where we tried to supply a fix for this.

The current FQN is:

org.eclipse.ptp.rm.jaxb.control.internal.variables.RMVariableResolver

yours is the older:

org.eclipse.ptp.rm.jaxb.core.variables.RMVariableResolver

I can verify that it is working after upgrading. Thanks.
