Liferay DM Info Viewer is not compatible with patch "Liferay Portal 6.1 EE GA2 Update 2012-09-18 Plugin Deployment-1"

See patch "Liferay Portal 6.1 EE GA2 Update 2012-09-18 Plugin Deployment-1"
at "http://www.liferay.com/group/customer/downloads/-/asset_publisher/YtYHVPRKNO6z/content/2012-09-18-6-1-20-update-plugin-deployment-1"

This patch introduced new hot deploy listener "com.liferay.portal.deploy.hot.ServletContextListenerHotDeployListener"

When the ServletContextListenerHotDeployListener is enabled via the hot.deploy.listeners property, the DM Info Viewer hook exhibits the following non-deterministic behaviours:

1/ The hook will not register with Liferay Portal at startup
2/ The hook will throw an Illegal State Exception at runtime due to an missing property packaged with the hook.

When the ServletContextListenerHotDeployListener is disabled, the hook behaves as expected.

Liferay DM Info Viewer and Liferay DM Downloader do not startup correctly when
com.liferay.portal.deploy.hot.ServletContextListenerHotDeployListener is enabled.
