Any issues to report on JDK 13 , would like to hear the status as we are

BoundedConcurrentHashMap
by Sanne Grinovero
Hi all,
does anyone remember where BoundedConcurrentHashMap was copied from?
we have a copy in Hibernate ORM; the comments state:
- copied from Infinispan
- original author Doug Lea
but I don't see any similar implementation in JSR166, nor any
reference to this classname on their archives:
- http://jsr166-concurrency.10961.n7.nabble.com/template/NamlServlet.jtp?ma...
The comments looks like suspiciously like this was originally a copy
of ConcurrentHashMap... I'm wondering which fixes we're missing out,
and if I should plan to get rid of this liability since Infinispan
also seems to have removed it.
Thanks,
Sanne

JDK 13 , JDK 14 & Valhalla Early Access builds are available.
by Rory O'Donnell
Hi Galder,
**OpenJDK* 13 Early Access build **28 is now available **at : -
jdk.java.net/13/*
* These early-access, open-source builds are provided under the GNU
General Public License, version 2, with the Classpath Exception
<http://openjdk.java.net/legal/gplv2+ce.html>.
* Changes in this build 28 [1]
*Reminder of a change in b24 - A jrt URI can only encode paths to files
in /modules tree **(JDK-8224946
<https://bugs.openjdk.java.net/browse/JDK-8224946>)*
A |jrt| URL is a hierarchical URI with syntax |jrt:/[$MODULE[/$PATH]]|.
When using the |jrt| file system, a |java.net.URI| object can be created
with the |java.nio.file.Path::toUri| method to encode a normalized path
to a file in the |/modules| tree. A |jrt| URL cannot encode a path to a
file in the |/packages| tree. The |jrt| file system provider has changed
in this release so that |toUri| fails with |IOError| when it is not
possible to encode the file path as a jrt URI. *This change may impact
tools have been making use of URLs that are not compliant with the
syntax. Tools with paths to files in **|/packages|**can use the
**|toRealPath()|**method to obtain the real path (in **|/modules|**)
before attempting to convert the file path to a URI.*
*OpenJDK 14 **Early Access build 4 **is now available **at : -
jdk.java.net/14/*
* These early-access, open-source builds are provided under the GNU
