The payara-embedded-nucleus distribution has been replaced by the Payara Micro distribution. This is a light-weight distribution that has Hazelcast integrated to allow for automatic web session clustering and JCache distribution.

We have also added a separate Payara domain template, which has a few optimisations:

• Increased PermGen Size of 512m (previously 192m)
• Increased Xmx value of 1024m (previously 512m)
• Removed Felix OSGI parameters
• Increased HTTP thread pool size of 50 (previously 5)
• Changed the JVM option –client to –server (this has been done for both domain templates)
• Added the JVM option to reject client initiated TLS renegotiation
