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.

	#!/usr/bin/python
	"""
	Simple restarter for jenkins - not a real Tanuki wrapper :-).
	- Install to /usr/local/bin and make the script executable.
	- Then create a cron entry to execute the script every 10 minutes:
	cat << EOF > /etc/cron.d/restartjenkins
	*/10 * * * * root /usr/local/bin/restartjenkins.py 2>&1 | logger -t restartjenkins
	EOF
	"""
	import os
	import sys
	import urllib2
	SERVICE_TO_RESTART = "/etc/init.d/jenkins restart"
	URL_TO_CHECK = os.getenv("URL_TO_CHECK", "http://127.0.0.1:8000/hudson/")
	def restart():
	os.system(SERVICE_TO_RESTART)
	if __name__ == "__main__":
	try:
	urllib2.urlopen(URL_TO_CHECK)
	open("/tmp/%s.timestamp" % os.path.basename(sys.argv[0]), "w").write(URL_TO_CHECK)
	except urllib2.URLError, e:
	error = sys.exc_info()
	error_message = "%s\n%s" % (error[0], error[1])
	sys.stderr.write(error_message)
	restart()
