java.lang.reflect.InaccessibleObjectException

[jtaafri]

This exception is thrown when running on Java 9. It is thrown in addFieldChildren when trying to access private fields:

    private void addFieldChildren(Object current, Deque<Object> stack, Set<Object> tracker, Object ignorableChild, MemoryMeterListener listener) {
        Class<?> cls = current.getClass();
        while (!skipClass(cls)) {
            for (Field field : cls.getDeclaredFields()) {
                if (field.getType().isPrimitive()
                        || Modifier.isStatic(field.getModifiers())
                        || field.isAnnotationPresent(Unmetered.class)) {
                    continue;
                }

                if (ignoreOuterClassReference && field.getName().matches(outerClassReference)) {
                    continue;
                }

                if (ignoreClass(field.getType())) {
                    continue;
                }

                field.setAccessible(true);

Is there any way around this in Java 9?

take a look at the –illegal-access=permit option in java 9

https://docs.oracle.com/javase/9/tools/java.htm#JSWOR624

but probably java10 means bad things

[jtaafri]

Yeah, it is weird. I have tried that option and still get an exception here.

Are you using classpath or modules?

[jtaafri]

My project does not contain any modules.

See https://stackoverflow.com/a/41265267/9046139 for a solution.

Basically you need to "open" the failing modules to unnamed ones (i.e. jamm). The solution must be adapted for each module that fails.

We have changed the code to ensure that Jamm can work even without the add-opens.
