The snapshot http://statistics.netbeans.org/exceptions/exception.do?id=258048 shows 18s and at least 180 opened files. According to code at http://kickjava.com/src/org/jfree/base/BaseBoot.java.htm the classloader's are asked for /jcommon.properties. This leads me to believe our classloading system is not optimized for negative queries into root package. Similar snapshot http://statistics.netbeans.org/exceptions/exception.do?id=258670 relates to Commons Logging's attempt to read "commons-logging.properties" Again Commons Logging: http://statistics.netbeans.org/exceptions/exception.do?id=257203 As Commons Logging is used in the NetBeans IDE as 3rd party library, this problem negatively affects performance of NetBeans IDE. Can we improve caching a bit, so negative queries require no ZIP opening and positive just directly open the correct JAR? The other issues (originally eleven) seem to be related to something else than default package loading. I've separated them to their own issue http://statistics.netbeans.org/analytics/detail.do?id=158285

*** Issue 172467 has been marked as a duplicate of this issue. ***
The Commons Logging reports seem to come from either JasperSoft modules or the Mozilla browser, neither of which is in the standard distro. The pause seems to be a normal cold disk cache effect. As for the JFreeChart report, again this is not in the standard distro. Not a P2, I think, since the standard distro does not seem to be affected and it is unclear what to do to reproduce. I'm not really sure what to make of the profiler snapshot; it claims JarClassLoader.JarSource.getJarFile is called once yet calls JarFile.<init> and JarClassLoader.JarSource.opened numerous times, when getJarFile contains no loop. pnejedly probably knows more about the cache system, and especially the special-case treatment of META-INF/** resources (issue #115017, issue #104340).
The default package problem needs to be resolved. There are/will be many duplicates.
