	When using java version 1.3.0.01 or greater on HP-UX 11.00
	to read a CDROM, the following can be seen:

	Exception in thread "main" java.util.zip.ZipException:
	invalid CEN header (bad signature)

Defect Description:
	PHKL_27207:
	( SR:8606235485 CR:JAGae04639 )
	There is a problem with the CDFS filesystem reading the
	CDROM data when mapped with mmap(2) on 11.00 with java
	version 1.3.0.01 or greater.

	Resolution:
	The cdfs_pagein() function was changed to detect end-of-file
	and only read in one page worth of data.
