Bug ID: 61381
Summary: PushbackInputStreams passed to ZipHelper may not hold
8 bytes
Product: POI
Version: unspecified
Hardware: PC
OS: Mac OS X 10.1
Status: NEW
Severity: normal

Example
ZipHelper tries to be efficient when checking the header by reusing
PushbackInputStreams that are given as input, but these streams may not hold
the 8 bytes that are pushed back, and can cause an exception.
Testable example is attached.
Workaround: Wrap InputStreams in BufferedInputStream before passing them to
anything that uses ZipHelper.
Solutions:
- always create a new PushbackInputStream
- stop using PushbackInputStream and switch to mark/reset + BufferedInputStream
