KeyGenerator issue

I have a function add a JCE provider for an AES algorithm, but the JCE
fails every time I attempt to launch it.
Provider jceProvider = new com.x.jce.provider.JCEProvider;
Security.addProvider (jceProvider);
Provider [] currentProviders = Security.getProviders();
// ... prints the array
SecureRandom rand = SecureRandom.getInstance("SHA1PRNG",
"JceProvider");
//psuedo random number generator
KeyGenerator aesKeyGen = KeyGenerator.getInstance("AES","JceProvider");
The SecureRandom getInstance function works fine, but the KeyGenerator
getInstance function fails with the following error:
[java] java.security.NoSuchProviderException: JCE cannot
authenticate the provider JceProvider
[java] at javax.crypto.SunJCE_b.a(DashoA6275)

[java] Caused by: java.util.jar.JarException:

Any ideas why the KeyGenerator would fail but the SecureRandom (which
looks for the same exact provider) fails? I've attempted to sign the
jars and verifying the signatures always returns true. I am completely
stumped.
