Short story: you're using java 7 which doesn't work with Subsonic right now. Use java 6 instead and you should be fine.

Long story (read this Sindre!):

http://www.oracle.com/technetwork/java/ ... .html#jdk7

Area: API: Utilities
Synopsis: Updated sort behavior for Arrays and Collections may throw an IllegalArgumentException
Description: The sorting algorithm used by java.util.Arrays.sort and (indirectly) by java.util.Collections.sort has been replaced. The new sort implementation may throw an IllegalArgumentException if it detects a Comparable that violates the Comparable contract. The previous implementation silently ignored such a situation.
If the previous behavior is desired, you can use the new system property, java.util.Arrays.useLegacyMergeSort, to restore previous mergesort behavior.
Nature of Incompatibility: behavioral
RFE: 6804124

I replaced Java 7 with Java 6 as you suggested, and it did indeed fix the problem. Being completely dependent upon it, Subsonic will hopefully be updated to be able to keep up with subsequent releases of Java.

Thanks!

Same problem here please fix.

Currently, the fix is on your side. Wait for a new release by Sindre or downgrade to Java 1.6.

I am running win7 and I have subsonic 4.7 build 3106 and I am getting an error also so I removed all Java per above ref. Restarted windows installed v6 and I still get the same error. So I removed 6 again and re-installed the latest v7 and here is my error:

As frustrating as these issues can be, the fact is that Subsonic runs fine on Windows when it's installed properly. There are three things that are installed that can go wrong. The program itself doesn't install properly for whatever reason. Java, the Java installation or however Subsonic uses it doesn't work properly. Three the C:\Subsonic directory has errors somewhere - usually what causes persistent failure when you've deleted the program and uninstalled/reinstalled Java.

I've done this hundreds of times now - so don't tell me you did the following and it doesn't work.

1. Uninstall Subsonic through the Control Panel/Programs and features removal process
2. Uninstall ALL Java references the same way.
3. Cut and paste the C:\Subsonic subdirectory to your documents or other folder so that it's removed from the C:\ root.
4. Install the LATEST Java release.
5. Install the LATEST Subsonic (currently 4.7)
6. Open the http://localhost:SSport# instance to verify it's working.

You can then take a flier and stop the Subsonic service and recopy your previously saved Subsonic folder back to C:\ to see if it runs or if it crashes again. If it crashes then you know for sure that the error is somewhere in C:\Subsonic.

Rinse and repeat as necessary.

Many users spend a lot of time trying to figure out what's wrong. That's all well and good, but sometimes you just get to the point where you want to fix it.

Everything was working fine until I updated to this version. That is when I started to see the error. As far as I know Subsonic still works fine as I haven't noticed any issues other than the notice. So I don't understand what went wrong and I am not going to remove everything. I don't have time to re-install everything and reconfigure the whole program again. Is there a way to save all my personal settings, directories etc to streamline the re-installation? If not I cant take time to manually do everything all over again. Sorry... and thanks for your help by the way
