Subject [jira] Updated: (HARMONY-5285) double reading of resources from jars
Date Mon, 10 Dec 2007 13:14:43 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-5285?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Naumova Natalya  updated HARMONY-5285:
--------------------------------------

    Description: 
The problem is in ZipEntry reading: some of JarEntry's are reading twice : resources in jars
for instance. Besides reading jar entries is not effective : it's reading via classlib portlib,
that uses systems calls always and there is no cashing of entries that were read before.
If one look to the file usage while jar loading he[she] see that the significant number of
reads happen from one offset (ecpesially for jars resources).
