DEFAULT SecureRandom not available

Hi, everyone.

The code initializing SSLContext works well when I set both BC Provider and
BCJSSE Provider
But when I set BCJSSE provider only, it fails to initialize SSLContext

Caused by: java.lang.IllegalStateException: unable to create TlsCrypto:
DEFAULT SecureRandom not available
at
org.bouncycastle.tls.crypto.impl.jcajce.JcaTlsCryptoProvider.create(JcaTlsCryptoProvider.java:82)
at
org.bouncycastle.jsse.provider.ProvSSLContextSpi.engineInit(ProvSSLContextSpi.java:425)
at javax.net.ssl.SSLContext.init(SSLContext.java:282)


Should I put new SecureRandom() instead of "null"?

But in the example code BC-FJA-(D)TLSUserGuide-1.0.5.pdf,
just add BCJSSE provider and put null to third parameter of SSLContext.init.

    KeyManagerFactory keyMgrFact = KeyManagerFactory.getInstance("PKIX",

    keyMgrFact.init(keyStore, keyStorePassword.toCharArray());

    TrustManagerFactory trustMgrFact =
TrustManagerFactory.getInstance("PKIX",
BouncyCastleJsseProvider.PROVIDER_NAME);
    trustMgrFact.init(trustStore);

    SSLContext sslContext = SSLContext.getInstance("TLSv1.2",
BouncyCastleJsseProvider.PROVIDER_NAME);
    sslContext.init(keyMgrFact.getKeyManagers(),
trustMgrFact.getTrustManagers(), null);
