Looking at a Java class (-source 6).
I am running a custom build of the FindBugs plugin, but I took care to include the purported fix of #235089 (by updating to current sources before applying my unrelated patch) and this still seems to happen. Also I am not using Java 8 sources at the moment.

Source -> Inspect -> Findbugs -> BANG!
Of course this only happens when running under JDK 8.

Although not using Java 8 sources, I'm using Java 8 to run the IDE and as default Java platform.

Findbugs is not working when NetBeans is running on Java 8, increasing priority.

executing a Findbugs inspection in a Java project.
The project is a Maven Jira plugin (<packaging>atlassian-plugin</packaging>)
Seems to happen when a new class is created, as well as when a file is opened by clicking on an exception link.
