FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
When using ZipInputStream, an exception is thrown while ZipFile.getInputStream(ZipEntry) works.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the given test code with a zip file whose entry is >4Gb.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Using " new ZipInputStream " should work when " ZipFile.getInputStream(ZipEntry) " works.
ACTUAL -
An exception is thrown.
