Description

During testing, I've found out that assertGC paths to root analysis fails with SecurityException and does not provide any reasonable results:

java.lang.SecurityException: Prohibited package name: java.lang
	at java.lang.ClassLoader.preDefineClass(ClassLoader.java:655)
	at java.lang.ClassLoader.defineClass(ClassLoader.java:754)
	at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)
	at java.net.URLClassLoader.defineClass(URLClassLoader.java:468)

	at java.lang.Class.getDeclaredMethods(Class.java:1975)
	at org.netbeans.insane.impl.InsaneEngine.recognizeClass(InsaneEngine.java:123)

The exception was thrown, because Insane library queries getDeclaredMethods() on org.netbeans.NbInstrumentation - the whole heap traversal then fails, since on JDK8 Module is not loaded from runtime, and an attempt to load it from boot.jar fails.
