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.
