Core-libs/javax.naming:
- New System and Security Properties to Control Reconstruction of Remote Objects by JDK's Built-in JNDI RMI and LDAP Implementations:
- Jdk.jndi.object.factoriesFilter: This system and security property allows a serial filter to be specified that controls the set of object factory classes permitted to instantiate objects from object references returned by naming/directory systems. The factory class named by the reference instance is matched against this filter during remote reference reconstruction. The filter property supports pattern-based filter syntax with the format specified by JEP 290. This property applies both to the JNDI/RMI and the JNDI/LDAP built-in provider implementations. The default value allows any object factory class specified in the reference to recreate the referenced object.
- Com.sun.jndi.ldap.object.trustSerialData: This system property allows control of the deserialization of java objects from the javaSerializedData LDAP attribute. To prevent deserialization of java objects from the attribute, the system property can be set to false value. By default, deserialization of java objects from the javaSerializedData attribute is allowed.

Security-libs/java.security:
Added 2 HARICA Root CA Certificates - The following root certificates have been added to the cacerts truststore:
HARICA:
- Haricarootca2015 - DN: CN=Hellenic Academic and Research Institutions RootCA 2015, O=Hellenic Academic and Research Institutions Cert. Authority, L=Athens, C=GR
- Haricaeccrootca2015 - DN: CN=Hellenic Academic and Research Institutions ECC RootCA 2015, O=Hellenic Academic and Research Institutions Cert. Authority, L=Athens, C=GR

Core-libs/java.lang:
Less Ambiguous Processing of ProcessBuilder Quotes on Windows:
- In the java.lang.ProcessBuilder implementation on Windows, the system property jdk.lang.process.allowAmbiguousCommands=false ensures, for each argument, that double-quotes are properly encoded in the command string passed to Windows CreateProcess. An argument with a final trailing double-quote preceded by a backslash is encoded as a literal double-quote; previously, the argument including the double-quote would be joined with the next argument. An empty argument is encoded as a pair of double-quotes ("") resulting in a zero length string passed for the argument to the process; previously, it was silently ignored. An argument containing double-quotes, other than first and last, is encoded to preserve the double-quotes when passed to the process; previously, the embedded double-quotes would be dropped and not passed to the process. There is no change to existing behavior when the jdk.lang.process.allowAmbiguousCommands property is set to true: jdk.lang.process.allowAmbiguousCommands=true.
