Class#getDeclaredMembers returns arbitrary results under JDK7. This results in non-deterministic execution of JUnit test methods, often revealing unintended dependencies between methods that rely on a specific order to succeed. JUnit 4.11 contains support for predictable test ordering [1], but at the time of this commit, JUnit 4.11 has not yet been released. Therefore we are testing against a snapshot version [2], which has been uploaded to repo.springsource.org [3] for easy access. Note that this artifact may be removed when JUnit 4.11 goes GA. - Care has been taken to ensure that spring-test's compile-time dependency on JUnit remains at 4.10. This means that the spring-test pom.xml will continue to have an optional <dependency> on JUnit 4.10, instead of the 4.11 snapshot. - For reasons not fully understood, the upgrade to the 4.11 snapshot of junit-dep caused NoSuchMethodErrors around certain Hamcrest types, particularly CoreMatchers and Matchers. import statements have been updated accordingly throughout affected test cases. - Runtime errors also occurred around uses of JUnit @Rule and ExpectedException. These have been reverted to use simpler mechanisms like @Test(expected) in the meantime. - Some test methods with order-based dependencies on one another have been renamed in order to fall in line with JUnit 4.11's new method ordering (as opposed to actually fixing the inter-test dependencies). In other areas, the fix was as simple as adding a tearDown method and cleaning up state. - For no apparent reason, the timeout in AspectJAutoProxyCreatorTests' testAspectsAndAdvisorNotAppliedToPrototypeIsFastEnough method begins to be exceeded. Prior to this commit the timeout value was 3000 ms; on the CI server under Linux/JDK6 and JDK7, the test begins taking anywhere from 3500-5500 ms with this commit. It is presumed that this is an incidental artifact of the upgrade to JUnit 4.11. In any case, there are no changes to src/main in this commit, so this should not actually represent a performance risk for Spring Framework users. The timeout has been increased to 6000 ms to accommodate this situation.
