The standard Cobertura maven plugin processes cobertura classes, not the XML report for threshold checks. This becomes a barrier when generating the cobertura report using tools like testacular, a coverage utility for Java Script. This plugin will parse the report and perform threshold checks. It targets the http://cobertura.sourceforge.net/xml/coverage-04.dtd

An low latency, lock free, primitive bounded blocking queue backed by an int[]. This class mimics the interface of {@linkplain java.util.concurrent.BlockingQueue BlockingQueue}, however works with primitive ints rather than objects, so is unable to actually implement the BlockingQueue. This class takes advantage of the Unsafe.putOrderedObject, which allows us to create non-blocking code with guaranteed writes. These writes will not be re-orderd by instruction reordering. Under the covers it uses the faster store-store barrier, rather than the the slower store-load barrier, which is used when doing a volatile write. One of the trade off with this improved performance is we are limited to a single producer, single consumer.
