I have JD v0.6.193 running on both XP SP3 on Java v1.6 and on NTv4 Server on Java v1.5.
JD on XP doesn't have the persistent update message that appears on NT.
FWIW, I ran a diff program on the two JD subdirectories.
The files listed on e:\JDownloader 0.5.859 are on NT Java v1.5
The files listed on L:\Program Files\JDownloader 0.5.917 are on XP Java v1.6.
I updated JD on the XP machine first and a few seconds later ran another update on the NT machine. Both versions report v0.6.193. Only JD on NT says there's another update available.
I checked two of the files listed as different, linksavein.class and relinkus.class.
For linksavin.class:
The version on NT is 1117 bytes timestamped June 10, 2009 8:34pm.
The version on XP is 4511 bytes timestamped May 29, 2009, 12:10am.
For relinkus.class:
The version on NT is 6025 bytes timestamped May 26, 2009 10:51pm.
The version on XP is 5571 bytes timestamped May 29, 2009, 12:10am.
So it would appear that the files being reported as different really are different, it's not just the file timestamp, as you might have expected.
This is the full diff output:
