RELEASE NOTES

security-libs/org.ietf.jgss:krb5

Issue Description
JDK-8005819

Support cross-realm MSSFU


The support for the Kerberos MSSFU extensions [1] is now extended to cross-realm environments.

By leveraging the Kerberos cross-realm referrals enhancement introduced in the context of JDK-8215032, the 'S4U2Self' and 'S4U2Proxy' extensions may be used to impersonate user and service principals located on different realms.

security-libs/javax.security

Issue Description
JDK-8200400

Allow SASL Mechanisms to Be Restricted


A security property named jdk.sasl.disabledMechanisms has been added that can be used to disable SASL mechanisms. Any disabled mechanism will be ignored if it is specified in the mechanisms argument of Sasl.createSaslClient or the mechanism argument of Sasl.createSaslServer. The default value for this security property is empty, which means that no mechanisms are disabled out-of-the-box.

Issue Description
JDK-8143849

Marlin Renderer in JDK 8u


Starting from version 8u311, the Marlin graphics rasterizer and its artifacts will be built and distributed as a part of the JDK/JRE bundles. It is not the default rendering engine, however there is an option to enable it by setting the following system property:

sun.java2d.renderer=sun.java2d.marlin.MarlinRenderingEngine


hotspot/svc

Issue Description
JDK-8144732

Binary format for HPROF updated


When dumping the heap in binary format, HPROF format 1.0.2 is always used now. Previously, format 1.0.1 was used for heaps smaller than 2GB. HPROF format 1.0.2 is also used by jhsdb jmap for the serviceability agent.


security-libs/javax.crypto

Issue Description
JDK-8205445

RSASSA-PSS Signature Support Added to SunMSCAPI


The RSASSA-PSS signature algorithm support has been added to the SunMSCAPI provider.


security-libs/java.security

Issue Description
JDK-8146293

Added Support for PKCS#1 v2.2 Algorithms Including RSASSA-PSS Signature


The SunRsaSign and SunJCE providers have been enhanced with support for more algorithms defined in PKCS#1 v2.2, such as RSASSA-PSS signature and OAEP using FIPS 180-4 digest algorithms. New constructors and methods have been added to relevant JCA/JCE classes under the java.security.spec and javax.crypto.spec packages for supporting additional RSASSA-PSS parameters.
