Red Hat Bugzilla – Bug 1016361
securerandom.source value in $JAVA_HOME/jre/lib/security/java.security is incorrect
Last modified: 2014-05-06 18:00:35 EDT
Description of problem:
The value set for securerandom.source in $JAVA_HOME/jre/lib/security/java.security is /dev/urandom but for some reason java sees this as /dev/random and jvm startup times are slow when they rely on this. Instead it should be /dev/./urandom
Version-Release number of selected component (if applicable):
Run an app with the default settings that relies on this file.
Steps to Reproduce:
1. Install Sun Java RPM or OpenJDK RPM
2. Run app utilizing securerandom.source
Startup times are very slow while /dev/random sorts out randomness.
/dev/urandom is used and startup times are fast.
As a workaround
can be set, but it seems the intention of using /de/urandom is to avoid this problem and therefor should be /dev/./urandom
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.
Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
The provided bug link in the original comment no longer works. However this has been brought up before. urandom does not provide as strong an initial seed as urandom and is therefore intentionally not the default:
Closing as WONTFIX.
