Subject [jira] Created: (JCR-2795) Initializing SeededSecureRandom may be slow
Date Wed, 20 Oct 2010 11:25:24 GMT
Initializing SeededSecureRandom may be slow
-------------------------------------------

                 Key: JCR-2795
                 URL: https://issues.apache.org/jira/browse/JCR-2795
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller
            Priority: Minor


For systems where reading from /dev/random is very slow (so that the alternative seed algorithm
is used), initializing the org.apache.jackrabbit.core.id.SeededSecureRandom singleton may
be very slow, because it is not synchronized. Each thread that calls SeededSecureRandom.getInstance()
will wait up to 1 second until the singleton is initialized.

At the same time, I would like to add more entropy to the alternative seed algorithm.
