This only occurs when data folder is set to anything other than default. For example, when someone wants to store their documents on an external drive.

This issue occurred as a result of having liferay.home pointing to a different location.

After talking with BChan, this is an issue. A user ought to be able to start up a liferay bundle anywhere and not have to configure a home folder to have the osgi folder.

Fix in https://github.com/brianchandotcom/liferay-portal/pull/9159 is not correct.

I checked in a proper fix in bf9c651d167b18630f29025fde5ac94abfb01b89

The other fix is not correct because I want to be able to preserve existing deployment behavior. Currently, if you start up Liferay without a home dir, that's OK, because Liferay will create it. With the OSGi changes, we forced users to have a proper liferay home, and that's too tedious.

We will now auto start and create the proper jar files for the liferay home dir.
