Cannot upgrade to SageTV 9

[Spartan]

Finally trying to update my Sage system from 7 to 9 and running into problems. So far I have tried:

- Installing SageTV 9 over top of my SageTV 7 installation.
- Dropping in the Sage.jar file over top of my SageTV 7 installation.
- Installing Java 8 u 111
- Uninstalling Java 8 and trying Java 7 u 79 (from redist zip)

None of the above things work, when I launch SageTV, I get the following errors (in succession):

What version of Java were you running before you tried to upgrade?

I presume you are using Windows, so you are talking about the 32-bit version of Sage. When you tried upgrading Java did you use the 32-bit version (the 64-bit version of Java won't work with 32-bit Sage)?

What plugins do you have installed? I think I recall reading that one of the mobile web server plugins caused a similar symptom where Sage crashed on start and gave a bunch of Java errors.

Yes, it's windows. I don't remember the java version I had started with but assume it was Java 8, fairly new. I did accidentally install the 64-bit version of java at one point, but got rid of it once I realized what I had done.

I do have the mobile web plugin installed as well as a few others. Is there a way to disable the plugin(s) via file edit, or do I have to get version 7 back and disable thru the UI?

You should be able to disable it by editing the Sage.properties file, but I don't know the exact line to edit, since I don't use that plugin.

I did a Google search and it looks like the crash I was thinking of was caused by "Sage TCPServer". Here are some references to the issue (may not be the same as your problem):

Hmm -- no luck there. I don't have SageTCPServer installed. Pretty sure I used to though.

Other things I've tried:

Deleting the entire contents of C:\Program Files (x86)\SageTV\SageTV\JARs
Whacking all of the plugin references from sage.properties

I also fired up procmon (sysinternals) to see where the jars were being loaded from. I was hoping that the last jar it loaded would be the offending one -- but no luck. It looks like it loads all the jars and then tries to run them or some such thing. (I'm a .net guy -- not a java guy...)



Just for funsies, I installed sage7 clean, plopped in my wiz.bin, then the sage9 .exe and STVs and it ran fine -- but of course I would have had to reconfigure sources, plugins, and whatnot. Really don't want to do all that....

That class version error means the JVM is too old and can't parse the format for the class files in Sage.jar. That means you probably have an older version of Java installed which SageTV is trying to use rather than the newer version.

It determines what version of the JVM to use by looking in the registry at HKLM\Software\JavaSoft\Java Runtime Environment\CurrentVersion. It then opens the key in HKLM\Software\JavaSoft\Java Runtime Environment\[CurrentVersionValue]\RuntimeLib to figure out what specific library to use to invoke the JVM.

Thanks for chiming in, Jeff -- not sure what I could be missing here: http://screencast.com/t/h09udn8ZN

Maybe try completely uninstalling Java, restart computer, then reinstall Java?

What is the value of the key "CurrentVersion" under "Java Runtime Environment"

That value is the key to finding what you screen captured

I've actually done that a number of time with all sorts of java versions.

It's 1.8:

So you need to check the 1.8 registry entry and not the 1.8.0_111 entry as that is where Jeff said sage is looking

[jusjoken]

I would also suggest go to the Java 32 bit control panel app and select the Java tab then view and see what the system thinks is your default java version.

Is this the guy you are looking for? http://screencast.com/t/WmM60NdUOk

I think everything is in order here: http://screencast.com/t/pf7YAiKHj

that all does look correct

Perhaps Jeff or someone else has other ideas

[Narflex]

Yeah...that's weird. It all looks correct....I forgot there is one other way it can load the JVM.

Do you happen to have a 'jre' folder in the SageTV install folder? If so, it will load the JVM that is inside of that folder and maybe that's an older one. That pretty much has to be it...because the class version file is 51, which is for Java 7 and there's no reason Java 8 shouldn't be able to load that.

I had a comparable issue, and there was a "jre" folder within the SageTV install directory. It should additionally be noted that if the folder is present, it will cause SageTV to report the version of java from within that folder, not what is in the registry.

It had been an ongoing mystery as to why System Information kept insisting on Java 1.6 being installed when "We had no such thing installed" to our knowledge. Now we know we actually did have it installed, just not where we expected it.
