Hi, all~
       I build the latest code in master branch and run it in my PC. When I
configure a mysql interpreter and run a simple demo in notebook,
I got the following error:

Then I edit the mysql interpreter and add the dependence of
commons-lang:commons-lang:2.5  as follows:


After restarting mysql interpreter, it work run normally.
Is this a bug?If so, I will create one jira to solve it.
Could anyone solve my puzzle?

Best Regards.
