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): How reproducible: 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 3. Actual results: Startup times are very slow while /dev/random sorts out randomness. Expected results: /dev/urandom is used and startup times are fast. Additional info: See http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6202721
As a workaround -Djava.security.egd=file:/dev/./urandom can be set, but it seems the intention of using /de/urandom is to avoid this problem and therefor should be /dev/./urandom

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: https://bugs.openjdk.java.net/browse/JDK-4705093 Closing as WONTFIX.
