------------------------------------------------------------------------

In view of JBIDE-19825, my first comment is partly erroneous.
We do need to scan once all 450 jars, and that takes 56 s. But in wildfly, only one jar is a Batch archive (jberet-core-1.1.0.Final.jar), so that the second scan over all 450 jars was not needed and took place due to an error described in JBIDE-19825.

Batch is a part of Java EE, and a lot of jars of Java EE are other frameworks that do not have and will never have Batch artifacts in them. Can we keep a name list of well-known jars (with '*' instead of version part) and never scan them? [~maxandersen], [~akazakov] what do you think of it?

> I made a comparison between Eclipse M6 and Eclipse M6 with batch feature installed while importing wildfly. WF is imported as maven project, maven is set to offline mode and local repository contains all needed dependencies.
> I did a 4 runs with following results:
> M6 was able to import WF 628,575,577,612 (in seconds) = average 598s
> M6 with batch feature: 843,832,924,877 (in seconds) = average 869s
