Description Jan Bartel CLA 2011-11-01 21:01:11 EDT 
Line 162 of SelectorManager can throw a NullPointerException iff:

* the Connectors are opened before Server.start() (eg in order to open as root before using setuid to change down to a lower privileged user)

* a request arrives before the SelectorManager has completed its its start() sequence. In this case, the SelectorSet[] array is allocated, but empty.

Just for completeness' sake, for those finding this issue, I got the line number wrong in the original comment. The problem actually occurs at line 158:

java.lang.NullPointerException
        at org.eclipse.jetty.io.nio.SelectorManager.register(SelectorManager.java:158)
        at org.eclipse.jetty.server.nio.SelectChannelConnector.accept(SelectChannelConnector.java:101)
