Lately I encountered a configuration tweak I was not aware of, the problem: I had a single Java installation on a Linux machine from which I had to start two JVM instances - each using a different set of JCE providers. A reminder: the JVM loads its security configuration, including the JCE providers list, from a master security properties file within the JRE folder (JRE_HOME/lib/security/java.security), the location of that file is fixed in the JVM and cannot be modified. Going over the documentation (not too much helpful, I must admit) and the code (more helpful, look for Security.java, for example here) reveled the secret.
