I think it's just a warning that you can ignore.

It's a bug in bouncycastle.

The latest spin of bouncycastle disabled all the gcj-isms so the
symlinks that gcj needs to find bouncycastle are no longer installed,
but the RPM still adds bouncycastle to the Classpath providers list.

Here's the test case:

import java.security.*;

public class Sec
{
  public static void main(String[] args)
  {
    for (Provider p: Security.getProviders())
      System.out.println(p);
  }
}

 $ gij Sec
WARNING: Error loading security provider org.bouncycastle.jce.provider.BouncyCastleProvider: java.lang.ClassNotFoundException: org.bouncycastle.jce.provider.BouncyCastleProvider not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:./], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}

We can just make sure the gcj symlinks are always installed:
