Spring complains that it needs to be started with agent when it actually is started that way [SPR-6147]

Spring complains that it needs to be started with an agent in order to use the InstrumentationLoadTimeWeaver even when it is, in fact, started with said agent.

Paul, this looks like a Spring problem rather then a Spring DM specific one. Most likely the class is loaded twice and is not considered valid somehow.

Affects Spring DM 1.2 RC1

Our context bundle which includes InstrumentationLoadTimeWeaver has an optional import for org.springframework.instrument.*;version="[3.0.0, 3.0.1)"... Could it be that the agent specified on startup is actually being added to the system classpath and hence doesn't get imported here? I guess I'll change that version range to start from 0...

Hopefully resolved through a version="0" import for that package. To be tested.
