@carstein looking forward your reply

[carstein]

I haven't tested this particular setup, but it does look like some sort of incompatibility between jython and Java. Can you try with jdk9?

[xauth000]

@carstein yea i changed to jdk9 and i got this error

ImportError: Cannot import site module and its dependencies: No module named site
Determine if the following attributes are correct:

• sys.path: [/usr/share/java/Lib, classpath, pyclasspath/]
  This attribute might be including the wrong directories, such as from CPython
• sys.prefix: /usr/share/java
  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
