INTEGRATION: CWS sb80 (1.1.2); FILE ADDED

2007/11/20 08:35:40 sb 1.1.2.1: #i82422# At least on Mac OS X Tiger, System.loadLibrary(hsqldb2) does not find the hsqldb2 library on directory above sdbc_hsqldb.jar, even though .. is on the jar's Class-Path; added NativeLibraries.load to work around that.
