Please take a review at https://cr.openjdk.java.net/~weijun/8215769/webrev.00/
It's currently P4 because I don't think many people import pkcs12 files from Firefox to Java, and even if so, one can always specify the storepass as a workaround. If you think this is more useful I can change it to P3 and push to JDK 12. This fix is safe. Thanks Max
