6.0 JDK/JRE Download testing
Bits taken from - http://jscpreview.sfbay/javase/downloads/ea.jsp :
jdk-6-rc-linux-i586-rpm.bin
jre-6-rc-linux-i586-rpm.bin

The (download + SwingSet2) tests were carried out on following platforms using the same above i586 bits.

PLATFORMS :
(1) RHL4 32bit OS on Intel box
(2) RHL3 32bit OS on AMD Athlon box
(3) RHL4 64bit OS on AMD Athlon box


STEPS:
On each of these above 3 platform , did the following :
- After downloading the bits from the website, set the execute permission.
- then execute these self Extracting RPM : for example: ./jre-6-rc-linux-i586-rpm.bin

PROBLEM:
For platforms (2) & (3) , the following console output(with Warning & Error) is obtained. For platform (1) only warning will be noticed.

PLEASE NOTE: [for all 3 platforms]
1) After this installation step , the location /usr/java/ & java version was checked . They were showing correctly. i.e
# ls /usr/java/
default jre1.6.0 latest
#java -version
java version "1.6.0-rc"
Java(TM) SE Runtime Environment (build 1.6.0-rc-b104)
Java HotSpot(TM) Client VM (build 1.6.0-rc-b104, mixed mode, sharing)

2)The whole process was run as Root user itself in all 3 platforms mentioned above.

3)SwingSet2 demo application was executed successfully [inspite of that error/warning in installation step]


Actually we use *-linux-amd64 bits on AMD Athlon box & i586 bits on Intel box.

Since platforms (2) & (3) both support 32bit applications, i just experimented Installing+SwingSet2 on these platforms using i586 bits. But Error was noticed in Installation step on (2) & (3) platfomrs , whereas only warning was found for (1). But SwingSet2 app was successfull in all 3 cases.
