> During a deploy of DayTrader, I get several (2 or 3) of the following warnings sent to STDOUT:
> 19:27:12,259 WARN  [DirectoryHotDeployer] Hot deployer unable to determine whether kernel is started
> java.lang.IllegalStateException: Cannot retrieve the value for non-persistent attribute kernelFullyStarted when GBeanInstance is DESTROYED
>         at org.apache.geronimo.gbean.runtime.GBeanInstance.getAttribute(GBeanInstance.java:668)
>         at org.apache.geronimo.kernel.basic.BasicKernel.getAttribute(BasicKernel.java:166)
>         at org.apache.geronimo.deployment.hot.DirectoryHotDeployer.isServerRunning(DirectoryHotDeployer.java:176)
>         at org.apache.geronimo.deployment.hot.DirectoryMonitor.run(DirectoryMonitor.java:141)
>         at java.lang.Thread.run(Thread.java:534)
> The problem must be in HotDeployer.isServerRunning(). It's getting a list of PersistentConfiguration GBeans and querying each one to see if it's active. Only when all are active is the server determined to be "active". During a deploy, there must be GBeans which are destroyed, probably as a replacement is created? (e.g. LocalAttributeManager).
> I have a patch (will post shortly) that sets a boolean to true once a server is detected as "running". After it's set to true, we'll never check the GBeans again... Clearly we're in need of a better way of determining server "state", any bright ideas? However, the boolean fixes the problem at hand...
