It could be very convenient for JCov users not only create there implementation for ANC(Acceptable Non Coverage) data , but also to use some common implementations from JCov. The example of using could be similar to javac -Xlint option:
jcov -Xanc:empty,toString
or
jcov -Xanc:all,-catch,-synthetic
List of default filters good to have in JCov:
1. Compiler-generated, rarely failing code. This includes Enum.values(), Enum.valueOf() methods, as well as any method tagged with the ACC_BRIDGE attribute. The $deserializeLambda$ method could also be included. These also do not correspond to actual source lines. Arguably, these should always be yellow.
2. Runtime exception paths. This is blocks that always throw an unchecked exception (including assertions). These are generally precondition checks, and are often uncovered. This could also include catch blocks that always throw an exception (these are often just exception-rewriting.)
3. Checked exception paths. Like (2), except for checked exceptions. This could be lumped in with (2), but I could imagine wanting to separate these out.
4. Empty methods.
5. toString() methods.
6. Catch blocks.
7. Deprecated methods.
