RELEASE NOTES

security-libs/javax.net.ssl

Issue Description
JDK-8163326

Updated the Default Enabled Cipher Suites Preference


The preference of the default enabled cipher suites has been changed. The compatibility impact should be minimal. If needed, applications can customize the enabled cipher suites and the preference. For more details, refer to the SunJSSE provider documentation and the JSSE Reference Guide documentation.


core-libs/java.net

Issue Description
JDK-8161016

Modified HttpURLConnection behavior when no suitable proxy is found


The behavior of HttpURLConnection when using a ProxySelector has been modified with this JDK release. HttpURLConnection used to fall back to a DIRECT connection attempt if the configured proxy(s) failed to make a connection. This release introduces a change whereby no DIRECT connection will be attempted in such a scenario. Instead, the HttpURLConnection.connect() method will fail and throw an IOException which occurred from the last proxy tested.


Modified HttpURLConnection Behavior When a Suitable Proxy Is Not Found


The behavior of HttpURLConnection when using ProxySelector has been modified in this JDK release. HttpURLConnection used to fall back to a direct connection attempt if the configured proxy(s) failed to make a connection. Beginning with this release, the default behavior has been changed to no longer use a direct connection when the first proxy connection attempt fails.

A new system property, sun.net.http.fallbackToDirect, can be set to a value of "true" should an application need to fall back to the old behavior (fall back to a direct connection when the first proxy connection attempt fails).
