High Description
Starting with Clover version 4.0.1 when running JUnit tests against clover instrumented code I am getting a null pointer exception when attempting to call this method:
// in DateUtil.groovy static <T extends Date> T copy(T date) { (T) date?.clone() }
It seems like something has changed with the instrumentation. Either of these two other variations of this same code doesn't have this problem:
static Date copy(Date date) { date?.clone() } static def copy(def date) { date?.clone() }
Here's the top of the stacktrace:
