Boaz Ben-Zvi commented on DRILL-5922:
-------------------------------------
While this leaks shows consistently in the IDE (Intellij), running the very
same query in embedded mode never showed this leak (in the log):
{code}

dfs.`/Users/boazben-zvi/IdeaProjects/drill/exec/java-exec/src/test/resources/multilevel/json`
