Timothy Farkas resolved DRILL-5170. ----------------------------------- Resolution: Duplicate Reviewer: Boaz Ben-Zvi Fix Version/s: 1.13.0 > JMockit-based unit tests fail when run under Java 8 > --------------------------------------------------- > > Key: DRILL-5170 > URL: https://issues.apache.org/jira/browse/DRILL-5170 > Project: Apache Drill > Issue Type: Bug > Affects Versions: 1.8.0 > Reporter: Paul Rogers > Assignee: Timothy Farkas > Priority: Minor > Fix For: 1.13.0 > > > Drill makes extensive use of the JMockit mocking library. Drill uses a very > old version of JMockit. JMockit appears to perform byte-code manipulations > that are incompatible with Java 8. For example: > {code} > cd exec/java-exec/ > mvn surefire:test -Dtest=TestSimpleProjection > Running > org.apache.drill.exec.physical.impl.project.TestSimpleProjection#project > Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 6.794 sec <<< > FAILURE! - in org.apache.drill.exec.physical.impl.project.TestSimpleProjection > project(org.apache.drill.exec.physical.impl.project.TestSimpleProjection) > Time elapsed: 0.215 sec <<< ERROR! > java.lang.VerifyError: null > at sun.instrument.InstrumentationImpl.redefineClasses0(Native Method) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at java.lang.reflect.Method.invoke(Method.java:498) > {code} > A similar error occurs when running the same unit test under Eclipse. > Fixing this issue is non-trivial. Mockito is subject to rapid change. The > semantics of mocks has changed significantly. Code that works fine in our old > version requires extensive rework to work with the current version. > For now, the only workaround is to compile Drill under the (obsolete) Java 7 > and use that version to run unit tests. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
