Hi,
I noticed that "not-linked" HashSet and HashMap are used during the
compilation of zone info data into tzdb.dat. This causes
non-deterministic order of records in tzdb.dat. While order there is not
important for java.util.TimeZone I thought that deterministic order will
be better.
I prepared webrevs for jdk9:
- http://cr.openjdk.java.net/~akasko/jdk9/tzdbgen_linked/webrev.00/
- http://cr.openjdk.java.net/~akasko/jdk9/tzdbgen_linked/webrev.00.zip
and jdk8u:
- http://cr.openjdk.java.net/~akasko/jdk8u/tzdbgen_linked/webrev.00/
- http://cr.openjdk.java.net/~akasko/jdk8u/tzdbgen_linked/webrev.00.zip
The actual different order is quite hard to reproduce, I spotted this
running TzdbZoneRulesCompiler on different versions of OpenJDK. So there
is no test.
Please let me know, if JBS bug should be created (have access as an
Author but never did it before), if jdk8u change should be posted
separately and later etc.
Thanks.
