Subject [jira] [Commented] (LANG-780) add public org.apache.commons.lang.builder.HashCodeBuilder append(Enum value) to HashCodeBuilder
Date Tue, 13 Dec 2011 01:53:30 GMT

    [ https://issues.apache.org/jira/browse/LANG-780?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13168053#comment-13168053

Sebb commented on LANG-780:
---------------------------

Are you sure that an Enum's hashCode can vary?

Or do you mean it can vary between different runtimes?

values if enum appended to HashCodeBuilder
