As you can see the:

Premain-Class: org.springframework.instrument.InstrumentationSavingAgent

is not loaded. this prevent opennms running with -javaagent in the case you have to enable weaving do to some customization.

I was able to run using the spring-instrument.jar. I do not know if there can be a side effect. spring-instrument is used only for javaagent run.
