[Bug 1308794] [NEW] Checkstyle unusable on Trusty

[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).
