JDK-8071699 (not public)
Area: security-libs/javax.net.ssl
Synopsis: Deprecate RC4 in SunJSSE provider
RC4 is now considered as a weak cipher. Servers should not select RC4 unless there is no other stronger candidate in the client requested cipher suites. A new security property,
jdk.tls.legacyAlgorithms , is added to define the legacy algorithms in Oracle JSSE implementation. RC4 related algorithms are added to the legacy algorithms list.
JDK-8043201 (not public)
Area: security-libs/javax.net.ssl
Synopsis: Prohibit RC4 cipher suites
RC4 is now considered as a compromised cipher. RC4 cipher suites have been removed from both client and server default enabled cipher suite list in Oracle JSSE implementation. These cipher suites can still be enabled by SSLEngine.setEnabledCipherSuites() and SSLSocket.setEnabledCipherSuites() methods.
JDK-8043202 (not public)
Area: security-libs/javax.net.ssl
Synopsis: Improved certification checking
With this fix, JSSE endpoint identification does not perform reverse name lookup for IP addresses by default in JDK.
If an application does need to perform reverse name lookup for raw IP addresses in SSL/TLS connections, and encounter endpoint identification compatibility issue, System property 'jdk.tls.trustNameService' can be used to switch on reverse name lookup. Note that if the name service is not trustworthy, enabling reverse name lookup may be susceptible to MITM attacks.
JDK-8067694 (not public)
Known Issues
Area: deploy/plugin
Synopsis: Java issue with Firefox 38, long delay with MyD loading
Java Plugin is unable to obtain proxy settings from Firefox 38 due to a bug in Mozilla framework. It may cause a long delay during RIA start up or can even cause start up failures. See the related issue:
Java 8 Update 51 Download 64 Bit
According to Mozilla, Firefox 39 will contain a fix for this problem.
Workarounds:
JDK-8081459 (not public)
![]()
Area: deploy
Synopsis: JNLP files won't launch from IE11 on Windows 10 Creators Update
Web-start applications cannot be launched when clicking JNLP link from IE 11 on Windows 10 Creators Update when 64-bit JRE is installed. Workaround is to uninstall 64-bit JRE and use only 32-bit JRE.
