Upgraded the Java version installed on my machine to ver 6, update 2 tonight. I still had the older update 1's folder and files on the machine so the directory structure looked like this:
C:\Program Files\Java\jre1.6.0_01
C:\Program Files\Java\jre1.6.0_02
I ran Java Portablizer v1.1 to update my ..\PortableApps\CommonFiles\Java files and it worked no problem. The program picked up on what was the latest version installed, copied the files, and updated the contents of JavaPortable.ini
Good work John! 
(I guess I was expecting it to choke on that setup...)

But Java itself has a ridiculous amount of small 1-2k files
and they waste A LOT of space on a FAT-formatted flashdrive .
I found one folder : actual file-size 256k size on disk : 1.7MB !
There's over 600 files in a full Sun Java JRE 1.6.0_02 and they
are not even particularly well compressed.
You can save about 25MB just by re-compressing all .jar's, f.ex with KJar,
and all exe's and dll's compress nicely with UPX.
unless you're running on a 486 it shouldn't be a problem .
And theres lots of files that may not be needed at all, depending on what
you are going to run on the JVM .
I have portable azureus working on a Sun Java that's only 23.6MB
and contains 90 files,both on a flash-drive ..
(a question directed more at John or anybody else who knows about license's)
Could the Java Portablizer re-compress .jar .dll and .exe files before it copies them to the device? And I'm talking about the legality of it (as per Sun's license).

If you're asking about the legality/license angle, I'll aske the other question...
Is it logistically possible? Could the Java Portablizer use an OSS library to re-zip the files or something like that?

I believe 7-zip can compress jars ?
In fact, John has done it on some of the apps that he does. He says he decompresses and (re)compresses it using 7-zip.
