EclEmma not working in version 4.31.0

[Brian Reiss]

After doing an update in eclipse recently, I noticed that my EclEmma is not working anymore. When looking at my eclipse log, this is one of the error messages that comes up:

There is another similar error after it:

Does anyone have any idea what may be wrong?

Thank you in advance.

The error message seems to be the same as in https://github.com/jacoco/jacoco/issues/1599#issuecomment-2033737996

so you also need to update EclEmma from 3.1.8 to 3.1.9

3.1.9 is available in the following P2 repository

https://download.eclipse.org/eclemma/releases/3.1.9/

which is referenced from the following composite P2 repositories

https://update.eclemma.org/

https://download.eclipse.org/eclemma/releases/

as well as in Eclipse Marketplace,

and the archive is at 

https://github.com/eclipse-eclemma/eclemma/releases/tag/v3.1.9

Hope this helps.

Regards,

Evgeny

Thank you so much. For some reason my Eclipse marketplace did not give me the option to upgrade from 3.1.8. Upgrading fixed the issue

Thanks again for the help!
