Hi, 
You can force the Java version used by Cassandra here: 
https://github.com/apache/cassandra/blob/cassandra-3.0/bin/cassandra.in.bat#L29 
Best,

 Thanks Michael and Paulo,

Upon further investigation, this is NOT a cassandra problem but a Java 
installation problem.  The machine in questioned been upgraded from 1.8.0_20 ro 
1.8.0_101.  This had upgraded the PATH env variable (java -version from the 
command line pointed to java 1.8.0_101) but it had not upgraded the JAVA_HOME 
env variable.  That still pointed to the old version of java.

Cassandra-env.ps1 uses JAVA_HOME to set  JAVA_BIN env variable (line 297) .  Is 
it worth putting in a test to see if Java -version gives a different result to 
JAVA_HOME ?

What is the git sha of your 3.10-SNAPSHOT build?

I see this was committed to trunk Jul 27, so perhaps your build is
older? If you are using something newer, maybe you could throw some
`echo` statements on those new version checks in conf/cassandra-env.ps1
to send some troubleshooting bits to stdout.

Forwarding to the u...@cassandra.apache.org list as this list is specific
for cassandra-development, not general cassandra questions.

Can you check the repository you built the snapshot from contains the
commit 01d5fa8acf05973074482eda497677c161a311ac?

Is java 1.8.0_101 on your $env:PATH ? Can you get this version with
java.exe -version from the command line?
