Safe Prime generation

[Colbix]

I've found that generating a safe prime using Java Bouncy Castle is slower than using OpenSSL. It looks like the Java version is using Sophie Germain as the prime generator while the C version is using a sieve method. Would it be possible to convert the C version into a Java version to reduce the safe prime generation time? Thank you for your consideration.
