Ehcache is an open source, standards-based cache used to boost performance,
offload the database and simplify scalability. Ehcache is robust, proven and full-featured and
this has made it the most widely-used Java-based cache.

/**
* Find jar names from the provided list matching a pattern.
*
* If the pattern is null and isNullInclusive is true, then
* all jar names will match.
*
* A pattern is a set of acceptable jar names. Each acceptable
* jar name is a regex. Each regex can be separated by either a
* "," or a "|". If you use a "|" this or's together the jar
* name patterns. This means that ordering of the matches is
* unimportant to you. If instead, you want to match particular
* jar names, and you want to match them in order, you should
* separate the regexs with "," instead.
*
* Eg "aaa-.*\\.jar|bbb-.*\\.jar"
* Will iterate over the jar names and match
* in any order.
*
* Eg "aaa-*\\.jar,bbb-.*\\.jar"
* Will iterate over the jar names, matching
* all those starting with "aaa-" first, then "bbb-".
*
* @param pattern the pattern
* @param uris the uris to test the pattern against
* @param isNullInclusive if true, an empty pattern means all names match, if false, none match
* @throws Exception
