The "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" answer did not work for me but The BouncyCastle's JCE provider suggestion did.

Here are the steps I took using Java 1.6.0_65-b14-462 on Mac OSC 10.7.5

1) Download these jars:

• bcprov-jdk15on-154.jar

• bcprov-ext-jdk15on-154.jar

2) move these jars to $JAVA_HOME/lib/ext

3) edit $JAVA_HOME/lib/security/java.security as follows: security.provider.1=org.bouncycastle.jce.provider.BouncyCastleProvider

restart app using JRE and give it a try
