BackgroundDownloader creates bundles dir under lib on a completed JRE.

Expected Behaviour:
BackgroundDownloader should immediately exit on a completed Kernel JRE.

Steps to reproduce:
1. Download and install Kernel JRE.
2. Wait till Kernel JRE to complete ( download all bundles)
3. instantiate completion process by executing a java program ( java -version)
4. Run Background Downloader (Z:\disk11\DTF3.1\DTF>java -Dkernel.background.download=false -Dkernel.download.securityenabled=null sun.jkernel.BackgroundDownloader)
