Hello, Based on previous discussions this thread which used to be an RFC is now an RFR. Thanks to Paul and Roger for comments.
Issue: https://bugs.openjdk.java.net/browse/JDK-8068373 Patch: http://cr.openjdk.java.net/~bpb/8068373/webrev.04/ Historical variants may be seen here: http://cr.openjdk.java.net/~bpb/8068373/ One problem (or not) with this approach is that old FileSystemPreferences caches which already contain U+0000 will still cause a failure on reading in Java 9+ but perhaps we do not care. Thanks, Brian
