-------------------------------------

             Summary: Phoenix can't be used directly with SquirrelSQL
                 Key: PHOENIX-1613
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1613
             Project: Phoenix
          Issue Type: Bug
            Reporter: Gabriel Reid


Due to an conflicting versions of (at least) commons-collections, Phoenix no longer works with [SquirrelSQL|http://squirrel-sql.sourceforge.net]. The error that is given is the following:
{code}
java.lang.IllegalAccessError: class
org.apache.commons.collections.iterators.EmptyOrderedIterator cannot access
its superclass
org.apache.commons.collections.iterators.AbstractEmptyIterator
{code}

SquirrelSQL apparently uses commons-collections 2.x, while Phoenix uses commons-collections 3.2.1. 

It's not totally clear what can be done to resolve this. It wasn't previously an issue, so there is a specific piece of code (apparently related to tracing) that now tickles this incompatibility. Probably the easiest fix is to get SquirrelSQL to upgrade to a more recent version of commons-collections, although there may be other ways to resolve this.

This issue has already been reported as-is to the SquirrelSQL project: http://sourceforge.net/p/squirrel-sql/mailman/message/33039278/
