[Saikrishna Arcot]

It is, but I wanted to get Trusty done first, since it has been released
already.

Title:
  Checkstyle unusable on Trusty

Status in “checkstyle” package in Ubuntu:
  In Progress
Status in “checkstyle” source package in Trusty:
  Triaged

Bug description:
  [Impact]
  On Trusty, the commons-beanutils source package was updated to 1.9.1. The org.apache.commons.collections class was (appropriately) moved to the libcommons-collections3-java source package. Because the startup script doesn't include the new jar file in the runtime, checkstyle crashes, saying it's unable to load the org.apache.commons.collections.FastHashMap class.

  [Test Case]
  Run checkstyle, specifying the required checkstyle XML file and one or more Java files. The following stacktrace will be printed:
  Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/collections/FastHashMap

  [Regression Potential]

  Limited. One java runtime library and a dependency was added, so there
  should be no regression. In addition, the commons-beanutils library
  might no longer be needed, but it has been left in (to avoid any
  potential regression).
