[Rui Li]

hi, 

I installed 4.0 on my mac also updated the java to 8. However, still go errors like this:

ruili1$ export STARDOG_HOME=/Users/ruili1/WORKSPACE/TOOLS/stardog-4.0-RC3

What is wrong? Thanks!

Rui,

This probably means there's more than one JVM installed on your Mac and you're using a <8 version to run Stardog.

You may use java -version and /usr/libexec/java_home to see what's going on.

Cheers,

Pavel

It looks like you're still running an old version of Java.  Double check that you're actually running the version you think. 

You also might want to update the Stardog version as well. It looks like you're running 4.0-RC3 and the latest version is 4.0.
