Introduce concurrency tests for Spring's JUnit 4 support
Whereas the existing TestContextConcurrencyTests verify support for concurrency in the TestContextManager and TestContext, this commit introduces SpringJUnit4ConcurrencyTests that verify support for concurrent test execution in Spring's JUnit 4 support, namely in the SpringRunner, SpringClassRule, and SpringMethodRule. The tests executed by this new test class come from a hand-picked collection of test classes within the test suite that is intended to cover most categories of tests that are currently supported by the TestContext Framework on JUnit 4. Note, however, that the chosen test classes intentionally do not include any classes that fall under the following categories. - tests that make use of Spring's @DirtiesContext support - tests that make use of JUnit 4's @FixMethodOrder support - tests that commit changes to the state of a shared in-memory database Issue: SPR-5863
