JMeter Keystore Warning

[jojoob]

I run the moodle-performance-comparison from my client PC against our existing test environment and got the following error. Nothing that prevents the test from completing but I wonder how to fix it anyway.

$ ./test_runner.sh first "first test" moodle-testplan_XS.jmx moodle-users-XS.csv site_data.properties
