My guess is either a bad install or a compatibility issue. Will be attempting a clean reinstall and will post results.

[Alex]

Yeah, this is related - I believe - to the game using an old version of xstream. Things to do:

1) Manually clean out the install folder, or install in another location
2) If you have a CLASSPATH environment variable, remove it
3) Make sure you're not using an old .sh/vmparams to run the game with

[Techhead]

Emptied directory, reinstalled. Crash at the same point, same error message in log.
CLASSPATH does not appear to be set in Environment variables, vmparams should be clean an fresh but is as follows in case it is not.

Code

java.exe -XX:CompilerThreadPriority=1 -XX:+CompilerThreadHintNoPreempt -Djava.library.path=native\\windows -Xms1024m -Xmx1024m -Xss1024k -classpath janino.jar;commons-compiler.jar;commons-compiler-jdk.jar;starfarer.api.jar;starfarer_obf.jar;jogg-0.0.7.jar;jorbis-0.0.15.jar;json.jar;lwjgl.jar;jinput.jar;log4j-1.2.9.jar;lwjgl_util.jar;fs.sound_obf.jar;fs.common_obf.jar;xstream-1.4.2.jar -Dcom.fs.starfarer.settings.paths.saves=..\\saves -Dcom.fs.starfarer.settings.paths.screenshots=..\\screenshots -Dcom.fs.starfarer.settings.paths.mods=..\\mods -Dcom.fs.starfarer.settings.paths.logs=. com.fs.starfarer.StarfarerLauncher

Ahhh, I think I see - are you on a 32 bit OS?

If you replace your vmparams with this, that should help:

java.exe -XX:CompilerThreadPriority=1 -XX:+CompilerThreadHintNoPreempt -Djava.library.path=native\\windows -Xms1024m -Xmx1024m -Xss1024k -classpath janino.jar;commons-compiler.jar;commons-compiler-jdk.jar;starfarer.api.jar;starfarer_obf.jar;jogg-0.0.7.jar;jorbis-0.0.15.jar;json.jar;lwjgl.jar;jinput.jar;log4j-1.2.9.jar;lwjgl_util.jar;fs.sound_obf.jar;fs.common_obf.jar;xstream-1.4.10.jar -Dcom.fs.starfarer.settings.paths.saves=..\\saves -Dcom.fs.starfarer.settings.paths.screenshots=..\\screenshots -Dcom.fs.starfarer.settings.paths.mods=..\\mods -Dcom.fs.starfarer.settings.paths.logs=. com.fs.starfarer.StarfarerLauncher

I'll see if I can get a hotfix out in a bit; want to wait and see if anything else crops up.

[Techhead]

Launches just fine now. Thanks a bunch, I know legacy systems can be a pain to deal with.

PS: Sorry for not mentioning system info upfront.

[Alex]

Cool - thanks for your understanding! Definitely my bad, forgot to update the 32 bit version of vmparams when updating a library...
