JCE jar file inside a deployment fails the signature check

1. Install WildFly (22-apr-2015 snapshot) out-of-the-box 2. use the CLI to deploy the attached war file (inside the maven project) 3. access: /bouncycastle-2015-01-30/bc Note that BC is not setup in the JDK, but is initialised in the deployment itself: row = Security.addProvider(new BouncyCastleProvider()); The code that fails: Cipher cipher = Cipher.getInstance("AES", "BC"); 14:49:13,582 ERROR
