example of a jstack attempt using v7 against a v6 vm (1.70 KB, text/plain)

Description Antoine "hashar" Musso (WMF) 2013-07-23 10:02:59 UTC 
Java on antinomy.wikimedia.org (host running gitblit) is not properly setup.  The `java` command points to JDK 6 and hence gitblit runs under Java 6.

The `jstack` command points to JDK 7 and cant take trace.  Mark Bergsma attempted to update the alternative to have jstack points to the JDK 6 version but it does not exist.

$ ls -1l /etc/alternatives/java /etc/alternatives/jstack
lrwxrwxrwx 1 root root 46 Jun 25 17:41 /etc/alternatives/java -> /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java
lrwxrwxrwx 1 root root 44 Jun 25 17:47 /etc/alternatives/jstack -> /usr/lib/jvm/java-7-openjdk-amd64/bin/jstack
$

We need jstack 6 to be installed to be able to take stack trace for bug 51769.

Setting this to Highest due to bug 51769 happening more than once a day currently.
Comment 3 Chad H. 2013-07-23 16:48:32 UTC 
Sorted out Java on antimony (thanks Faidon!), everything's running openjdk7 now, no 6 needed.
Comment 4 Antoine "hashar" Musso (WMF) 2013-07-23 19:03:24 UTC
