This reverts commit a2f9166fc80b4708d3c854e1d86c069968aa2b7d.
I'm backing out the fix for:
[JDK-8379007](https://bugs.openjdk.org/browse/JDK-8379007) [lworld] JNI
NewWeakGlobalRef should throw IdentityException for value types
due to unexpected test failures in the Valhalla CI. At least some of the
failures in Tier3 are occurring without the --enable-preview option.
