The plugin saw only one substantial commit (its initial addition to the
repository). This very first version of the plugin was already broken
(undefined variable "core1") and was never fixed.
Thus it feels sane to assume, that the plugin was never used.
Many plugins are still failing these tests.
These expected failures are listed in a file
(t/test-exception-wrapper.expected-failures)
A wrapper script is used for running the tests and comparing the result
with the expectation (based on the file being listed in the above file).
This allows to test all new plugins, while ignoring all known failures.
