[jboss-user] [Performance Tuning] New message: "Re: JBoss 3.2.6 - pauses for a minute during startup"

User development, A new message was posted in the thread "JBoss 3.2.6 - pauses for a minute during startup": http://community.jboss.org/message/528938#528938 Author : Brian Stansberry Profile : http://community.jboss.org/people/bstansberry@jboss.com Message: -------------------------------------------------------------- Oops; I misread. It's not checking System.getProperty("securerandom.source") -- it's Security.getProperty("securerandom.source"). And the value for that generally comes from  $JAVA_HOME/jre/lib/security/java.security   where $JAVA_HOME is the root of the JDK you're using.   On my system, that's   securerandom.source=file:/dev/urandom   If on your system it's file:/dev/random and your system provides /dev/urandom, yes, you might consider changing it to file:/dev/urandom. Or, if you want to limit the change to just this application and not all uses of the JDK, like you say, use -Djava.security.egd=file:/dev/urandom That's the workaround listed for this JDK bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4705093   The output from /dev/urandom may contain less entropy then that from /dev/random, but it won't block. Whether the decrease in entropy is important for you depends on your application. I'd think it would only be a concern for a very small subset of applications. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528938#528938
