Hi Dalibor,
Am sending a test program that results in the same assertion problem.
The test program takes a jar file location, reads contents from each file in
the jar and prints the same to standard output. It uses ZipFile and ZipEntry
classes present in java.util.zip.* pkg.

Attachments :
Test.java --> source code of java file.
Test.jar --> dummy jar file for input to the program. This contains the same
"Test.java".

Thanks & regards,
Santosh
