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.
