ClassFormatError

[lex...@gmail.com]

Hello,

I am trying CDI-Unit for the first time and I am getting this error:

 

java.lang.Exception: There were class format errors. This is often caused by API only jars on the classpath. If you are using maven then you need to place these after the CDI unit dependency as 'provided' scope is still available during testing.

I am running this on Java 6,  is it supported?

Hi,

I tried your project with OpenJDK6 and it worked fine for me from the command line and eclipse.

The error message is saying that the CDI-Api jar is somehow on the classpath. API jars like CDI or Servlet typically have missing method implementations as they are not intended to be on the classpath except at compile time.

Check that your classpath is clean and that you haven't got any manual entries there.

Also you don't need to specify the Weld dependency unless you want to run a specific version of Weld. In that case you should exclude the dependency from the CDI-Unit entry.

Hello,

The error happened for me too. I moved the maven CDI-Unit entry to the top of the dependencies. 

Then it changed to: 

"java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/servlet/ServletException"

I just can't reproduce this. Can you paste your dependencies here?

I've pushed a change in to HEAD to give better error messages for API only classes on the classpath. It'll now tell you the class and the offending classpath entry.

If this works for you (feedback to https://github.com/BrynCooke/cdi-unit/issues/62) then I will do a new release.

I have deployed a snapshot to Sonatype if it makes it easier for you to test.
