I reject this. Not enough justification. Kumar On 2/19/2015 11:19 PM, mikhail cherkasov wrote:

Hi all,

Bug: https://bugs.openjdk.java.net/browse/JDK-8073187

The problem is that packer changes global state( default time zone ) without proper synchronization: http://hg.openjdk.java.net/jdk9/client/jdk/file/a159e5358e25/src/java.base/s...

however javadoc says that it's save to use it in concurrent way if each thread has it's own packer instance: http://hg.openjdk.java.net/jdk9/client/jdk/file/a159e5358e25/src/java.base/s...

The fix isn't perfect but it the only possible solution: 1. first packer saves default time zone 2. the last set it back.

Thanks, Mikhail.
