Some geode queries will fail on java 16 and later

In some cases a geode query uses reflection to read a field or call a function.

If that happens on java 16 then the query will fail throwing a RuntimeException that is an instance of java.lang.reflect.InaccessibleObjectException. See: https://softwaregarden.dev/en/posts/new-java/illegal-access-in-java-16.

To workaround this failure set the JVM command line option: --illegal-access=permit

The query code that calls setAccessible is in two places:

org.apache.geode.cache.query.internal.AttributeDescriptor#getReadMember

org.apache.geode.cache.query.internal.MethodDispatch#MethodDispatch
