RFR 7902258: Only one parametrized ANC filter is allowed simultaneously

[Alexandre (Shura) Iline]

Hi,

Please review this fix for https://bugs.openjdk.java.net/browse/CODETOOLS-7902258
Webrev: http://cr.openjdk.java.net/~shurailine/7902258/webrev.01/

The fix adds new concept: AncFilterFactory. Instances of that factory are loaded as services. ANC filters themselves are no longer loaded as services. This makes this change functionally incompatible. Since there is no longer a need to distinguish ANC filters by name, there is no longer any need in DefaultANCFilter (which should have probably been called “named ANC filter” in the first place).

There is one possible additional fix which will need to be done later: get rid of ParameterizedAncFilter class. If the instantiation are done by a factory, there is no need for that class as factory should be able to instantiate the filter using parameter value passed as an additional parameter or just as a part of parameter to instantiate(String) method.

Thank you

Shura
