Error marker being reported on incorrect line number during manifest validation

[alshamams]

In the MANIFEST.MF file, the error reporting in some cases is displayed on line 1 by default.

Such a situation arises due to the difference in the validation process when :

1. manifest is first loaded, and
2. it is inline edited.

In the first case, the validation takes place in the OSGI layers without obtaining the erroneous line number, as is the case with bundle description validation, thereby displaying it on line 1.
In the second case, the line number is also taken into account and the error marker is displayed accordingly.
The former approach can lead to uncertainty with respect to the exact location of the error.
