Solution :

- Download  bouncycastle library at http://www.bouncycastle.org/latest_releases.html (For me its bcprov-jdk15on-147.jar and bcprov-ext-jdk15on-147.jar).

- Copy theses files (eg: bcprov-jdk15on-147.jar and bcprov-ext-jdk15on-147.jar) in /path_to_your_jvm/jre/lib/ext. (e.g: /opt/jdk/jdk1.6.0_18/jre/lib/ext)
- vi /path_to_your_jvm/jre/lib/security/java.security and add the following line : security.provider.9=org.bouncycastle.jce.provider.BouncyCastleProvider

java.security

security.provider.1=sun.security.provider.Sun
security.provider.2=sun.security.rsa.SunRsaSign
security.provider.3=com.sun.net.ssl.internal.ssl.Provider
security.provider.4=com.sun.crypto.provider.SunJCE
security.provider.5=sun.security.jgss.SunProvider
security.provider.6=com.sun.security.sasl.Provider
security.provider.7=org.jcp.xml.dsig.internal.dom.XMLDSigRI
security.provider.8=sun.security.smartcardio.SunPCSC
security.provider.9=org.bouncycastle.jce.provider.BouncyCastleProvider

- Restart jboss.
