I copied the following from the travis-ci log in a run where all that was changed was the pom version, 0.8.6 to 0.8.7-SNAPSHOT and the other 3 passed, this one failed (seems like it occurred randomly):

ACCUMULO_VERSION='1.5.2'
ACCUMULO_LEGACY='-Daccumulo.legacy'
HADOOP_VERSION='2.6.0'
GEOTOOLS_VERSION='12.2'
GEOSERVER_VERSION='2.6.2'
PLATFORM_VERSION='""'
