You are probably right. Indeed the tool seems confused about the convention used. It had suggested multiple changes of the form ```Throwable t```-> ```Throwable e```, but I thought that this was a false positive (e.g. in ```org.junit.rules.TestWatcher``` and ```org.junit.tests.experimental.rules.TestWatcherTest``` test).

I understand that making a global change would be daunting and possibly controversial, would like me to submit such a pull request?
