A DESCRIPTION OF THE PROBLEM :
If a jar file is created using the JDK jar utility, the
getSize and getCompressedSize methods of the JarEntry (and
ZipEntry) class return -1 (unknown.)

The methods report the correct sizes if the archive is a
zip file (created with Info-ZIP zip or other popular third-
party compression utility.)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. create a sample text file with some content and name it:
afile.txt
2. jar cvf test.jar afile.txt
3. Compile and run the sample code below against test.jar

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expect the program to display:

Size is: size

where size is the actual file size, but instead the program
will display:

Size is: -1

REPRODUCIBILITY :
This bug can be reproduced always.
