OpenJDK on OpenShift: “NoSuchAlgorithmException: EC AlgorithmParameters not available”

问题

I'm running into java.security.NoSuchAlgorithmException: EC AlgorithmParameters not available with Wildfly 8.2 (OpenJDK 1.8.0_31) on OpenShift (the exception is thrown by AmazonHttpClient).

It looks like there is a bug with OpenJDK 1.8 and ECC: https://bugzilla.redhat.com/show_bug.cgi?id=1167153

On of the suggested workarounds requires editing jre/lib/security/java.security to disable jdk.tls.disabledAlgorithms=EC,ECDHE,ECDH. Or removing jre/lib/ext/sunec.jar

Unfortunately I'm not able to do this on OpenShift (missing permissions).

What would be the best workaround here? Can I alternatively switch to Oracle JDK (on OpenShift) which does not have this problem?

UPDATE:

I removed Sun java.security.Provider-s and added BouncyCastle instead:

static {
  Security.removeProvider("SunEC");
  Security.removeProvider("SUN");
  Security.removeProvider("SunJSSE");
  // ...
  Security.addProvider(new BouncyCastleProvider());
}

Unfortunately BouncyCastle is not a JSSE provider (create an SSLContext instance using a Bouncy Castle provider) and SSLContext.getInstance() fails with NoSuchAlgorithmException: TLS SSLContext not available.

I also tried @Rudy De Busscher suggested answer, although I'm not in favor of manual setting the env variable since it's something that can later easily be forgotten. Instead, I added the JAVA_OPTS_EXT setting to $OPENSHIFT_DATA_DIR/.my_custom_env and loaded it with source ${OPENSHIFT_DATA_DIR}.my_custom_env in the .openshift/action_hooks/pre_start hook. It didn't worked but since I would still need to use BouncyCastle for JSSE, I have given up this solution.

Fortunatelly I was able to switch back to OpenJDK 1.7 (via .openshift/markers/java7) which "solved" the problem for now.

Found a solution.

You can define a properties file to override some of the keys defined in the default JRE file jre/lib/security/java.security

This file can be specified in the JAVA_OPTS_EXT environment property of the OpenShift Gear.

These are the steps that we took to fix the issue.

Create the file

rhc ssc gearName
cd $OPENSHIFT_DATA_DIR
vi override_security.properties
content is jdk.tls.disabledAlgorithms=EC,ECDHE,ECDH
pwd -> and note down (copy) the full path location of the just created file.
exit

Set the environment variable

rhc env set JAVA_OPTS_EXT=-Djava.security.properties=file:fileLocation -a gearName

Restart your gear/app

rhc app restart -a gearName

That did the trick for us.
