Instrumentation fails when starting an application in IntelliJ using the agent

[mariusoe]

Starting an application directly in IntelliJ using the inspectIT agent will throw errors due to an instrumentation of the class com.intellij.rt.execution.application.AppMainV2$1. This is happening because IntelliJ adds an agent to the Java process as well.

When starting an application in debug-mode, the instrumentation of the Thread class will fail due to an error on an attempt to add a method to the class. Nevertheless, the error also appears when disabling our custom class file transformer. Due to this, it is most likly a problem to the agent attached by IntelliJ.
