There was a bug in the test case. However, we fixed it already last week. Maybe the file has not been replaced with the latest version.

Try to delete the following files in ARTE and replace them with the latest from the repository. ARTE/data/testcases/public_pum_1.ttc ARTE/data/testcases/given_test_cases/pum/pum.zip

[tsdh]

Well, I'm on your current HEAD 88aad3b without any local modifications, so these files (I guess the former is actually ARTE/data/testcases/public_pum_1.ttc because there is neither a ARTE/data_testcases/pub_pum1.tcc nor a ARTE/data/testcases/pub_pum1.tcc) are already up to date.

To be really sure, I did:

% git reset --hard origin/master 
HEAD is now at 88aad3b fixed failing inheritance check for fully qualified references instead of imports
% git stat
On branch master
Your branch is up-to-date with 'origin/master'.
Untracked files:
  (use "git add <file>..." to include in what will be committed)

    ARTE/log/
    ARTE/user_data/

nothing added to commit but untracked files present (use "git add" to track)

[SvenPeldszus]

Ok, I can not reproduce this error.

Can you please give me your solution.

Can you please post the contents of the file ARTE/data/testcases/public_pum_1.ttc. By the way, I really had two typos in the file in my post above.

[tsdh]

The contents are:

Ok, the file is up to date.

Maybe the .class files are deleted too early. I will create a version of ARTE with some debug messages for this problem.

[tsdh]

Of course it is up to date. I did a git reset --hard origin/master and origin is this very repository. ;-)

Ah, I know what's the problem. The method java.lang.reflect.Method.getParameterCount() is new in JDK 8 and I'm running JDK 7. In JDK 7, you can get the parameter count using someMethod.getParameterTypes().length.

[SvenPeldszus]

ok, thanks for the help I will change it

[SvenPeldszus]

I have pushed the new version. Hopefully this fixes your problems

[tsdh]

Now I get: java.lang.NoSuchMethodError: java.lang.Class.getTypeName()Ljava/lang/String;. That's another method which is new in Java 8.

Could you please test with a JDK 7 (or JDK 8 with the corresponding compatibility settings) yourself? I'd really appreciate if I could start working on my solution anytime soon...

[SvenPeldszus]

Sorry, I accidentally forgot to switch my JDK

[tsdh]

No problem, https://github.com/Echtzeitsysteme/java-refactoring-ttc/commit/32197e5b12dcb0aa6298996729ac308951cef818 works now. I'm closing this issue.

Thanks!
