[jira] [Created] (GROOVY-9933) Exceptions logged on Java 8
Benjamin Muskalla created GROOVY-9933:
-----------------------------------------
Summary: Exceptions logged on Java 8
Key: GROOVY-9933
URL: https://issues.apache.org/jira/browse/GROOVY-9933
Project: Groovy
Issue Type: Bug
Components: groovy-runtime
Affects Versions: 3.0.7
Environment: MacOS
Reporter: Benjamin Muskalla
When using Groovy 3.0.7 on a JDK 8, the following exception is logged. This causes problems for other parties scanning logs for exceptions and users trying to find real problems. The exception in question doesn't seem to be a problem though as it is expected to not find Java 9 classes on Java 8. In Groovy 2.x, this used to not log errors as it checked the java major version before loading the class.
