org.apache.catalina.util.SessionIdGenerator createSecureRandom consumes a lot of time, how to avoid it?

Some time tomcat took a long time to start up. From the log, I can see. What shall I do?

INFO: Creation of SecureRandom instance for session ID generation using [SHA1PRNG] took [25,121] milliseconds.
