https://issues.apache.org/jira/browse/FLINK-11316 Project: Flink
Issue Type: Test
Components: Tests
Reporter: Gary Yao
*Description*
{{JarFileCreatorTest}} fails when run with Java 9. Because {{JarFileCreator}} is not used in production, the class and its tests can be deleted.
Stacktrace:
{code}
java.lang.IllegalArgumentException

*Steps to reproduce*
With the Java 9 compiler in the path, run:
{code}
mvn test -Pjava9 -DfailIfNoTests=false -Dfast -Dtest=org.apache.flink.runtime.util.JarFileCreatorTest
{code}
Alternatively, run the test from IntelliJ with the {{java9}} profile enabled.
*Acceptance Criteria*
* {{JarFileCreator}} and {{JarFileCreatorTest}} are deleted
* Usage of {{JarFileCreator}} in {{ClassLoaderUtilsTest#testWithURLClassLoader}} is replaced with an alternative
