A large number of compiler tests fail with '-XX:-UseCompressedOops -XX:-UseCompressedClassPointers' (also with '-Xint'), for example:

test/hotspot/jtreg/compiler/valhalla/inlinetypes/TestGenerated.java

# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (/oracle/valhalla/open/src/hotspot/share/gc/shared/memAllocator.cpp:433), pid=697761, tid=697780
# assert(elements_end <= obj_end) failed: payload must fit in object

# Problematic frame:

# Core dump will be written. Default location: Core dumps may be processed with "/usr/share/apport/apport -p%p -s%s -c%c -d%d -P%P -u%u -g%g -- %E" (or dumping to /oracle/valhalla/open/JTwork/scratch/core.697761)
