Java's TLS not compatible with OpenSSL's TLS?

I initialize OpenSSL 0.9.7 in a non-blocking C++ server like this: SSL_METHOD *method = TLSv1_method(); SSL_CTX CTX = SSL_CTX_new(method); A Java 1.4.1_01 client is initialized like that: SSLContext ctx = SSLContext.getInstance("TLSv1"); When the Java client connects to the server SSL_accept()
