Re-filing this as a problem rather than a question, from http://forums.gradle.org/gradle/topics/nullpointerexception-in-profileeventadapter-completed-profileeventadapter-java-72

This is a problem since upgrading to gradle 2.0.

Env:

------------------------------------------------------------
Gradle 2.1

  Build time:

Here’s the command line & trace. Note the cache & home dir options are to work around GRADLE-3106.

Some additional information. It appears that it has some dependence on other gradle instances even thought they are using different cache & home directories. This is evidenced from the fact that after building thousands of jobs, it happened on at the same exact time on multiple separate gradle invocations:

Note the time stamps.
