When doing the SWAT on linux-amd64 machine, I installed the *.rpm.bin bundle.
During the bin bundle extraction process, I got the following error message:

  inflating: j2sdk-1_5_0-beta-linux-amd64.rpm
j2sdk ##################################################
Error: unpack could not create /usr/java/j2sdk1.5.0/jre/lib/rt.jar. Please refer to the TroubleshootingSection of the Installation Instructions on the download page.execution of j2sdk-1.5.0-beta script failed, exit status 1

Done.
-------------------

Then I verified the .rpm bundle size with the original .rpm bundle size in /net/mizu/usr/re/jdk1.5.0/bundles/linux-amd64/latest/

They have the same file size: 31979737
-rw-r--r-- 1 root root 31979737 Dec 11 03:23 j2sdk-1_5_0-beta-linux-amd64.rpm

Then I verified the rt.jar under /usr/java/j2sdk1.5.0/jre/lib dir
bunt:/usr/java/j2sdk1.5.0/jre/lib # ls -ll rt.jar
-rw-r--r-- 1 root root 37898773 Dec 11 12:49 rt.jar

rt.jar is created properly.

The error installation message really confused users during the installation process.

System tested:
Host: bunt
Linux bunt 2.4.19-SMP #1 SMP Mon Mar 31 23:48:08 UTC 2003 x86_64 unknownSuSE SLES-8 (AMD64)
VERSION = 8.1

STEP TO REPRODUCE:
=================
0. clean the previous installed jdk located under /usr/java dir
1. cd /net/mizu/usr/re/jdk1.5.0/bundles/linux-amd64/latest
2. install the j2sdk-1_5_0-beta-linux-amd64-rpm.bin bundle
3. during the bin bundle extraction process, notice any error message is generated.
