Interesting JDK15 fact: 8254078: DataOutputStream is very slow post-disabling of Biased Locking

Hello ZooKeeper,
I found this interesting issue on JDK mailing lists
https://github.com/openjdk/jdk/pull/542/files

It is about the fact that in JDK15 Biased Locking is disabled by default
and DataOutputStream is slower in some cases.

Are you running on JDK15 ? Have you ever seen any performance regression ?
It looks like we are using DataOutputStream

Regards

Enrico
