Hi all,

     I tried configuring IDP cluster with Terracotta 3.6 and followed the
steps as mentioned in the Wiki

https://wiki.shibboleth.net/confluence/display/SHIB2/IdPCluster

I did some variations based on a previous discussion in the blog

http://shibboleth.1660669.n2.nabble.com/Clustering-with-Terracotta-3-4-1-td6077871.html


   - i installed tim-vector 2.7.1 and tim-tomcat 6.0 2.3.0 which are latest
   versions available.
   - make-boot-jar.sh had been moved to <TC_HOME>/platform/bin/. I used
   that version.

The boot jar got created successfully and when i tried to start the tomcat
server with the sample script provided in the setup page , the startup is
failing with the below entry in catalina.out

Error occurred during initialization of VM
java.lang.NoSuchMethodError:

Please find attached the tc-config.xml i used for the setup.

I am using java 1.6.0.25.

Any idea why this error is occurring. i am not sure if its because of the
Java version i am using.
