Determine if the following attributes are correct:
 * sys.path: [/home/bvn13/dev/proj1/SpringProj-2.4.jar!/BOOT-INF/lib/Lib, __classpath__, __pyclasspath__/]
   This attribute might be including the wrong directories, such as from CPython
 * sys.prefix: /home/bvn13/dev/proj1/SpringProj-2.4.jar!/BOOT-INF/lib
   This attribute is set by the system property python.home, although it can
   be often automatically determined by the location of the Jython jar file
You can use the -S option or python.import.site=false to not import the site module
