Unclean Shutdown #68

Closed neodem closed 7 years ago

neodem commented 7 years ago

After my mvn run I'm seeing something odd. There is a class not found exception (below). I've checked that the dependency/class exists in the embedmongo-maven-plugin pom. I'm guessing there is some kind of shutdown hook and it's occurring after mvn releases it's class loader. I don't mind tracking this down more but I'm curious if you could provide some insight.

Hi. Issue #44 currently tracks this problem. It appears that there's something unsafe going on inside the underlying flapdoodle API. Doors anything here help: https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo/issues/116 ?
