[xwiki-users] XWiki 9 Java errors - xwiki-users@xwiki.org

15 Mar 2017

Greets,
I've installed xwiki 9.1.2 in a new VM.  I am using Java 1.8.0_25.
I ran the standalone installer and said start_xwiki.sh and it started, and I got the java
stacktraces below.   I have not modified xwiki.cfg or anything else.

Can anyone shed some light on these errors?   Thanks!

Doug
