// Test case for issue #293: https://github.com/typetools/checker-framework/issues/293
// Thanks to Ed Price for the test case.
// Design space:
// try
// ...
// catch: 7 varieties
// * absent
// * catch Throwable
// * catch Exception
// for each of the "present" types of catch:
// * no action
// * call method
// * assign string
// finally: 2 varieties
// * absent
// * no action
// Naming indicates which one; overall 14 tests.
// Empty, to give this file its name.
