Fixing the annoying Java 2-line logging format

java.util.logging is far from perfect, but for me the main reason to not use it is the hard-to-read default formatter which shows the date on a whole row. There are more compact formatters - but you need to write code to install them, or edit the command line.

So every time I install a JVM, I change the logging formatter:

1. in $JAVA_HOME/jre/lib/logging.properties, replace

java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
with

java.util.logging.ConsoleHandler.formatter = org.apache.juli.JdkLoggerFormatter

2. copy TOMCAT_HOME/bin/tomcat-juli.jar to JAVA_HOME/jre/lib/ext.
