Example 16 with StartLevel

use of org.osgi.service.startlevel.StartLevel in project aries by apache.

the class BundleFrameworkImpl method setupStartLevelToPreventAutostart.

   * grand scheme of things causes extenders to act on the inner bundles before the outer composite is even
   * resolved ...
