2017-10-10 10:31:23,898: 1086 [ main] ERROR spectit.agent.java.SpringAgent - inspectIT agent initialization failed. Agent will not be active.The problem seams to be the changed API of the ClassLoader class empty constructor. From Eclipse forum:
Using the empty constructor ClassLoader() is not equivalent to what we have today on Java 8 because it will use a parent of the ClassLoader.getSystemClassLoader() which is not the boot class loader. Instead we will have to resort to calling the new Java 9 static method: ClassLoader.getPlatformClassLoader()
As we are on JDK6 we'll need to use reflection here.
