### Question:
OsgiUtils { public static Set<String> getAllBundleExports( FileFilter filter, Set<String> pkgs ) { if ( pkgs == null ) { pkgs = new HashSet<>(); } Set<File> candidates = getClasspathCandidates( filter ); for ( File candidate : candidates ) { String exports = getBundleExports( candidate ); if ( exports == null ) { if ( LOG.isDebugEnabled() ) { LOG.debug( I18n.msg( I18n.MSG_17000_NO_EXPORT_FOUND, candidate ) ); } continue; } if ( LOG.isDebugEnabled() ) { LOG.debug( I18n.msg( I18n.MSG_17001_PROCESSING_EXPORTS, candidate, exports ) ); } splitIntoPackages( exports, pkgs ); } return pkgs; } private  OsgiUtils(); static Set<String> getAllBundleExports( FileFilter filter, Set<String> pkgs ); static Set<String> splitIntoPackages( String exports, Set<String> pkgs ); static Set<File> getClasspathCandidates( FileFilter filter ); static String getBundleExports( File bundle );  }### Answer:
@Test public void testGetAllBundleExports() { OsgiUtils.getAllBundleExports( null, null ); }
