OpenJDK 8 now supports ECC With this update, OpenJDK 8 supports Elliptic Curve Cryptography (ECC) and the associated ciphers for TLS connections. ECC is in most cases preferable to older cryptographic solutions for making secure network connections. Additionally, the java-1.8.0 package priority has been expanded to 7 digits.
Description of problem: First, this bug isn't with "rh-java-common", but I couldn't choose "java-1.8.0-openjdk" because you need to add "java-1.8.0-openjdk" and related packages to the list of potential "Component" choices for Red Hat Software Collections, since that's been part of SCL since RHEL 6.6. java-1.8.0-openjdk from SCL 1.1 on RHEL 6.6 is unable to connect to external sites that use certain encryption algorithms. The issue is the same as the one described in this Fedora bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1167153 How reproducible: Always, when connecting to a site that offers elliptic curve algorithms with https. Steps to Reproduce: Multiple different methods of reproducing this issue are listed in the bug ID quoted above. For example, when our continuous integration system tries to connect to Maven Central to download jars, the connection fails with: Caused by: java.security.NoSuchAlgorithmException: EC AlgorithmParameters not available at sun.security.jca.GetInstance.getInstance(GetInstance.java:159) at java.security.Security.getImpl(Security.java:695) at java.security.AlgorithmParameters.getInstance(AlgorithmParameters.java:146) at sun.security.util.ECUtil.getECParameters(ECUtil.java:139) ... 53 more
Re-assigned to java-1.8.0-openjdk.
ECC support will appear in java-1.7.0-openjdk in RHEL 6.7. The work now needs forward-porting to java-1.8.0-openjdk. I expect this to appear during the RHEL 6.8 timeframe.
