STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
GitHub Repo: https://github.com/zrlw/jmockit-mybatis-bindingexception-sample.git
IDE: Eclipse 2019-03, 2019-12 or other 4.1x
Tool integration: Maven
Jdk: OpenJDK or Oracle JDK, version >= 1.8

1. git clone the repo.
2. Import into eclipse workspace:
   click 'File' -> 'Import...' -> 'Maven' -> 'Existing Maven Projects' -> 'Next',
   choose 'jmockit-mybatis-bindingexception-sample' directory for 'Root directory'.
3. Build:
   right click the project name on the 'Package Explorer' view,
   click 'Maven' -> 'Update Project...'.
4. Test:
   right click the project name on the 'Package Explorer' view,
   click 'Run As' -> 'Maven test'.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Second testcase should pass 'firstName', 'lastName' as parameter names just like test it alone.
ACTUAL -
Second testcase of the test suit passed 'arg0', 'arg1' to Mybatis which cause BindingException.

FREQUENCY : always
