jenkins LTS 1.424.6 and java.lang.NoSuchMethodError: com.google.common.collect.ImmutableList.copyOf(Ljava/util/Collection;)Lcom/google/common/collect/ImmutableList;

While updating the parent version of JobConfigHistory+Plugin from Jenkins LTS version 1.424.2 to 1.424.6 I encountered
the following:

Using mvn dependency:tree, I saw that org.kohsuke.stapler:stapler:1.172 depends on
com.google.guava:guava:r06, this version does not include the symbol.
Version 1.424.6 of the WAR provides com.google.guava:guava:jar:11.0.1, which includes this symbol.
See Update to LTS 1.424.6 for the fix.

Restarter script for Jenkins

• I am fighting with my Jenkins instance being down every other day.
• Getting bored of sshing to the host and restart the instance, I wrote a small restarter script.
