Tibor Digana commented on SUREFIRE-1071:
----------------------------------------
These kinds of failures need having deeper look.
Definitely this class was modified with maven-shade-plugin.
Download project from Github and check the configuration of every pom.xml
having "maven-shade-plugin" if repackaging org.apache.maven.shared package.
Then Check Release Notes if some higher version of shade plugin has candidate
bug fix.
You can check requirements for Java version in the bytecode.
Alternatively you may use some IBM bytecode verifier tool if exists,
before/after bytecode manipulation.
