- #
- #  The program was produced on an experimental basis in the course of the

- #  Each user of the program will agree and understand, and be deemed to

- #  production of secondary products from the program.
- #
- #  In the case where the program, whether in its original form or

-  ICU uses the public domain data and code derived from Time Zone

- # 7.  Database Ownership
- #
- #    The TZ database itself is not an IETF Contribution or an IETF

- #    that is in the public domain, and is intended to remain in the
- #    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
- #    not apply to the TZ Database or contributions that individuals make
- #    to it.  Should any claims be made and substantiated against the TZ
- #    Database, the organization that is providing the IANA
- #    Considerations defined in this RFC, under the memorandum of
- #    understanding with the IETF, currently ICANN, may act in accordance
- #    with all competent court orders.  No ownership claims will be made
- #    by ICANN or the IETF Trust on the database or the code.  Any person
- #    making a contribution to the database or code waives all rights to
- #    future claims in that contribution or in the TZ Database.

Subject: [PATCH 065/143] 8243947: [TESTBUG]
 hotspot/jtreg:hotspot_appcds_dynamic fails when the JDK doesn't have default
 CDS archive

Generate a default CDS archive when necessary before running AppCDS dynamic tests.

Subject: [PATCH 074/143] 8241072: Reimplement the Legacy DatagramSocket API

Replace the underlying implementations of the java.net.DatagramSocket and java.net.MulticastSocket APIs with simpler and more modern implementations that are easy to maintain and debug.

+ * machine is started with the system property {@systemProperty
+ * jdk.net.usePlainDatagramSocketImpl} set to use the old implementation. It may
+ * also be set in the JDK's network configuration file, located in {@code
+ * ${java.home}/conf/net.properties}. The value of the property is the string
+ * representation of a boolean. If set without a value then it defaults to {@code
+ * true}, hence running with {@code -Djdk.net.usePlainDatagramSocketImpl} or
+ * {@code -Djdk.net.usePlainDatagramSocketImpl=true} will configure the Java
