/**
 * Modified by deheng on Feb 1, 2019.
 * This test aims to expose the java.lang.RuntimeException when running test cases in Math_58, a real bug from defects4j. But this test file (CocospoonLocalizerTest.java) is created based on the version of Nopol of March 2017.
 * Use `mvn clean package -DskipTests` to build nopol and use `mvn test -Dtest=CocospoonLocalizerTest` to run this test.

// But this java.lang.RuntimeException seems to only happen when the Nopol and CoCospoon are built/installed in JDK 1.7. When Nopol and CoCoSpoon are built/installed in JDK 1.8, this test will pass.
