Looks like Java 8 is very picky with JavaDoc comments, e.g. <p/> makes the build fail (<p> is better)
Also build 1.8.0-ea-b80 will fail due to some bug. Use at least: build 1.8.0-ea-b84

Locally all tests are passing now - except one:

org.springframework.integration_.mbeanexporterhelper.Int2307Tests#testInt2307_DefaultMBeanExporter()

In Java 8 there seems to be a timing issue coming up. Adding Thread.sleep(500) helps. Not sure why this would be necessary. May need to revisit with more recent JDK8 builds. If setting lower values, intermittent test failures start to appear.
