Paulex,
And I have got some ant script and more excluded list for emma, if
anyone has interests, I can upload it to JIRA.
Yes please, upload the list into JIRA. I'm going to experiment with the list
and source coverage of HY API too.
When I tried to experiment with HY API by unit tests code coverage
measurement via Emma I saw such errors.
The reason why runtime dies is that Emma instruments core classes and
inserts calls to its classes, which, in their turn, depend on the being
initialized core classes (for example, initialization of java.lang.Object is
working, it calls instrumented code, i.e. Emma class to store profiling
information, but the class in its turn depends on Object).
Thanks,
Vladimir

Yes!
