Evgeny,
Thanks for the response. JMockit 1.47 isn’t released yet, according to the JMockit website. That is why I upgraded to 1.46 rather than 1.47. And 1.47 isn’t available on Maven Central yet. I looked at the classpath of the project in Eclipse, which is generated from the Maven pom.xml, and it has JMockit 1.46. In the pom.xml, for the maven-surefire-plugin, I have explicitly specified the ASM 7.1 as a dependency. I even explicitly added ASM 7.1 to be a test dependency in the pom.xml (outside of maven-surefire-plugin), and that didn’t fix it either. Since this builds correctly on the command line, and does not in Eclipse 2019-03, and the dependencies are correct in Eclipse for the project, this has to be an Eclipse problem. There is something internal to Eclipse that is pulling in an older version of ASM that doesn’t have the NestHost/NestMembers problem fix, as you pointed out in the stack trace.

Support of Java 11 JEP 181 (NestHost/NestMembers) was implemented in official ASM 7.0 and to our knowledge no changes in this support was done since then. IMO this could easily be an issue in JMockit, and BTW you use not the latest one, which is 1.47. On Friday, June 21, 2019 at 5:20:57 PM UTC+2, Marc R. Hoffmann wrote: Does this error also occur when you run your tests in Eclipse in normal “run” mode (no coverage)? In this case JaCoCo or EclEmma is not involved in your runtime classpath at all. And even when you run your application with with JaCoCo the JaCoCo agent includes its own repackaged version of ASM which will not interfere with other ASM versions on the class path.

But in Eclipse, when running the JUnit tests, this error occurs. I am assuming that this is occurring is the version of JaCoCo that EclEmma is using has a dependency on an older version of ASM that has not fixed the problem with NestHost and NestMembers. Just an FYI: I am using EclEmma/JaCoCo combined with JMockit. This shouldn't be the cause, as this is a known problem with ASM.
