This code seems wrong:
uintptr_t data() const { return value() >> data_shift; }
It's doing a signed shift, so the sign bit is going to be extended into the unsigned result, giving a value that is too large.
InJDK-8261235, non_data_bits was changed to work around this problem, but the real problem is the sign bit. non_data_bits should not count pointer_bits because pointer_bits is actually included in kind_bits (see JDK-8287288).
uintptr_t data() const { return value() >> data_shift; }
It's doing a signed shift, so the sign bit is going to be extended into the unsigned result, giving a value that is too large.
