> 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).

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).
