Description Jaroslav Tulach 2011-11-29 21:03:52 UTC 
Looks like the code in Netigso.java:

Enumeration en = b.findEntries("", null, true);
while (en.hasMoreElements()) {
  URL url = (URL) en.nextElement();
}

reads content of all JARs. That does not seem to be very effective especially if the amount of bundles is low.

This prevents the OSGi framework to resolve the bundles (this is what findEntries is required to do). But it may not find all packages from fragments or external bundles.

No comments so far. I guess nobody cares and I'll integrate tomorrow.
Comment 4 Jaroslav Tulach 2012-01-10 11:15:07 UTC 
Integrated as core-main#c3b7c6f096ef

This fix could/should improve first start without caches a bit, if anyone on NetBeans IDE side is interested.

Integrated into 'main-golden'
