Coverage is not working for some defects.

[rjust]

For some older defects, the build does not specify the source and/or target version. As a result, the compiled classes of these defects have a target version of 11 (whereas all other classes have a target version of 6). Cobertura (using an old version of asm) cannot instrument these classes.

Consistent with all other defects, we should explicitly set the source and target versions for these older defects.

(I have compiled a list of affected defects and should have a fix pretty soon.)
