Apache Felix fails to run in background (including nohup case)

How to run Apache Felix in background with nohup. Solution is here. In my case I faced the problem when tried to run Squash TM in background. That application is built over Apache Felix and the exceptions told something like: ZipFile closed
at org.apache.felix.framework.util.WeakZipFileFactory$WeakZipFile$


Spring DM context shutdown thread WARN 06/09 14:35:39 [] - Exception
thrown from ApplicationListener handling ContextClosedEvent
java.lang.IllegalStateException: ApplicationEventMulticaster not initialized - call 'refresh' before multicasting events via the context:
OsgiBundleXmlApplicationContext(, config=osgibundle:/META-INF/spring/*.xml): startup date
[Fri Sep 06 14:35:34 BST 2013]; root of context hierarchy

Certain amount of investigation shown that the common solution in such the case is to exclude the application binding to the console. So do the following:

  1. As it's recommended here check if you have ConsoleHandler enabled for your Log4j and disable it using the following entry: java.util.logging.ConsoleHandler.level = OFF (if you're using property file to configure your logging. otherwise use the xml equivalent)
  2. Drop the bundles holding -shell suffix from your Bundles folder. They could look like the following:
  3. As the alternative of the previous step you may add -Dgosh.args=--nointeractive  option to the jvm arguments on calling your app from sh sctipt
  4. Run your application in the regular way like nohup ./ &
This should help.
