The -XshowSettings launcher has a new security category. Settings from security properties, security providers and TLS related settings are displayed with this option. A security sub-category can be passed as an argument to the security category option. See the output from java -X:

   -XshowSettings:security

       show all security settings and continue
   -XshowSettings:security:*sub-category*
       show settings for the specified security sub-category and continue. Possible *sub-category* arguments for this option include:
       all: show all security settings and continue
       properties: show security properties and continue
       providers: show static security provider settings and continue
       tls: show TLS related security settings and continue

Third party security provider details will be reported if they are included in the application class path or module path and such providers are configured in the java.security file.

Fixed an issue on Debian Linux distros where jpackage could not always build an accurate list of required packages from shared libraries with symbolic links in their paths, causing installations to fail due to missing shared libraries.

Delete nonfunctional desktop integration functionality from Linux installers. The installers will stop depositing files in /usr/share/icons, /usr/share/mime, and /usr/share/applications subtrees.

The following root certificates have been added to the cacerts truststore:

+ GlobalSign

  + globalsignr46
    DN: CN=GlobalSign Root R46, O=GlobalSign nv-sa, C=BE

+ GlobalSign
  + globalsigne46
    DN: CN=GlobalSign Root E46, O=GlobalSign nv-sa, C=BE

DTLS 1.0 has been disabled by default, by adding "DTLSv1.0" to the jdk.tls.disabledAlgorithms security property in the java.security configuration file. DTLS 1.0 has weakened over time and lacks support for stronger cipher suites. Any attempts to use DTLSv1.0 will fail with an SSLHandshakeException. Users can, at their own risk, re-enable the version by removing "DTLSv1.0" from the jdk.tls.disabledAlgorithms security property.

Native executables and libraries on Linux have switched to using RPATH instead of RUNPATH in this release.

JDK native executables and libraries use embedded runtime search paths to locate other internal JDK native libraries. On Linux these can be defined as either RPATH or RUNPATH. The main difference is that the dynamic linker considers RPATH before the LD_LIBRARY_PATH environment variable, while RUNPATH is only considered after LD_LIBRARY_PATH.

By making the change to using RPATH, it is no longer possible to replace JDK internal native libraries using LD_LIBRARY_PATH.

The installation directory name of the Oracle JDK in RPM and DEB packages has changed from /usr/lib/jvm/jdk-${FEATURE}-oracle-${ARCH} to /usr/lib/jvm/jdk-${VERSION}-oracle-${ARCH}.

Every update release will be installed in a separate directory on Linux platform.

Installers will create a /usr/java/jdk-${FEATURE}-oracle-${ARCH} link pointing to the installation directory to allow programs to find the latest JDK version in the ${FEATURE} release train.
