Uwe - thanks for the suggestion.

There's nothing that should cause jar modification but maybe the file 
timestamps are going wonky.  The build is a plain and simple build; 
modules do use jars from earlier module builds but nothing that hasn't 
work for ages (years).

A google search shows some cases of exit 143 for a variety of reasons 
but I don't see a consistent pattern and some simply don't apply to the 
setup here (e.g. MS windows).

In the current period of SIGTERMisms (143 = 128+signal 15), ubuntu4 is 
the only machine involved.  We have had intermittent occurrences before 
but not for a while and I can't see the history.  It's never happened 
building locally.

	Andy

If you compile a maven plugin and then use it afterwards, you should split your maven build to do this in 2 separate maven invocations. This is a known bug to all JVMs: The native zlib code reading the JAR files segfaults if a JAR file changes while opened by a classloader.
