[jboss-osgi-issues] [JBoss JIRA] Commented: (JBOSGI-297) OSGiBootstrapBean spinning on System.in read

[Scott M Stark (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBOSGI-297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12518422#action_12518422 ] 

Scott M Stark commented on JBOSGI-297:
--------------------------------------

>From these comments I'm not sure if your looking at the cpu utilization. Its not an issue of the runtime not starting quickly. I see the same type of startup logs. The issue is that once the boot has occurred, the cpu goes to 100% utilization due to the read on System.in returning -1. No one else is seeing that cpu usage?
