FilteredFieldStream is intended to filter out some fields which does not
represent valid java objects.
Currently the only filtered field is "constantPoolOop" from
jdk.internal.reflect.ConstantPool class.
The change fixes FilteredFieldStream implementation to handle cases when
filtered fields is the last field of the class ("constantPoolOop" is the only
field of jdk.internal.reflect.ConstantPool)
Testing:
- new test added that compares results of GetClassFields JVMTI function (it
uses FilteredFieldStream) with Class.getDeclaredFields();
- test/hotspot/jtreg/vmTestbase/nsk/jvmti/GetClassFields tests
