In Documentation Installation Instructions for Java 2 Platform Standard Edition 5.0, it says:
"You should have approximately 165 MB of free disk space before installing the documentation. "

For JDK 5.0 docs on sparc, it needs at least 238 MB for docs and 45 MB for zip file (yes, we can delete zip file after unzip to save space. During unzip, you still need this space.)
