Java error on first startup
 

I had the attached error when I first loaded Alice 2.3. Since then it has not come back, so it doesn't seem to be causing me any issues now. Maybe the devs can see this and make some sense of it.

[CODE]Alice version: 2.3.5
os.name: Windows NT (unknown)
os.version: 6.2
os.arch: x86
java.vm.name: Java HotSpot(TM) Client VM
java.vm.version: 20.0-b11
user.dir: C:\Users\Doc\Desktop\Alice\Alice 2.3\Required

JAVA startup Error
 

If you are not able to startup with JAVA on your system, first make sure that the JRE file and the JVM are installed on your system. these two are the most important to run JAVA on any system. If you face any problem with these things, you may take help from [URL="https://mailhelp.net/hotmail-support/"]Hotmail Support[/URL] for a clean JAVA installation.

Its very important to refresh your JRE, i already encounter almost the same error, what i did is completely remove java and re-installed the updated version.
