RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Type: Release Note
Doc Text:
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 Tim Mooney 2015-04-01 23:29:40 UTC
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:


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 java.security.Security.getImpl(Security.java:695)
                at sun.security.util.ECUtil.getECParameters(ECUtil.java:139)
                ... 53 more

Comment 3 Joe Orton 2015-06-08 11:26:15 UTC
Re-assigned to java-1.8.0-openjdk.

Comment 5 Andrew John Hughes 2015-06-08 15:19:16 UTC
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.
