[jira] [Commented] (LANG-727) ToStringBuilderTest.testReflectionHierarchyArrayList fails with IBM JDK 6

["Joerg Schaible (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13078436#comment-13078436 ] 

Joerg Schaible commented on LANG-727:
-------------------------------------

Actually I am not sure what the test shall demonstrate. Is it a special type construction that is arbitrarily present in ArrayList or does it demonstrate that it can also handle an ArrayList. If it is the latter then we have to check for a different String representation with IBM JDK 6 runtime, because it exposes implementation details of the type.

> Actually the test is wrong, because it makes wrong assumptions about the implementation of ArrayList in the runtime.
