Build Identifier: unknown

If a JUnit launch contains the line
  <booleanAttribute key="org.eclipse.debug.core.capture_output" value="false"/>
junit will fail rather ungracefully with:

java.lang.NullPointerException

An easy workaround is to remove this option from the launch, but arguably Buckminster could either handle this case, or fail more gracefully. (Old Java saying: every function will return null eventually ;)


Reproducible: Always

Steps to Reproduce:
1. Create a JUnit launch and switch off Console Allocation in the "Common" tab
2. ./buckminster --displaystacktrace ... junit -l ...
3. Kaboom
