Typically, this means that for some reason, the java.security files in the WiKID packages did not get copied to your java location.
# locate java.security
You will see one in /opt/WiKID/conf/templates/java.security and one or more in your java directories. Copy the one from the WiKID directory to the one in your working java directory. BouncyCastle needs to be set as the second provider as in the WiKID copy:
security.provider.1=sun.security.provider.Sun security.provider.6=com.sun.net.ssl.internal.ssl.Provider security.provider.3=com.sun.rsajca.Provider security.provider.4=com.sun.crypto.provider.SunJCE security.provider.5=sun.security.jgss.SunProvider security.provider.2=org.bouncycastle.jce.provider.BouncyCastleProvider
