     [ https://issues.apache.org/jira/browse/COLLECTIONS-515?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Cyrille Artho updated COLLECTIONS-515:

    Attachment: Report3.java

A JUnit test that results in a ClassCastException even though no explicit cast to String is made.

> When LazySortedMap is used by equals, the result is
> java.lang.ClassCastException: org.apache.commons.collections4.map.LazySortedMap cannot be cast to java.lang.String
> This seems to be odd, as the use of the different transformations should not result in internal casting to String. See the attached unit test to reproduce.
