[jira] [Commented] (LANG-833) ToStringBuilder should use StringBuilder

["Duncan Jones (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15759047#comment-15759047 ] 

Duncan Jones commented on LANG-833:
-----------------------------------

The documentation for {{ToStringBuilder}} makes no guarantees about thread-safety. Do we need to preserve non-documented behaviour?

We could add another constructor that accepts a {{StringBuilder}}, then internally only use a {{StringBuffer}} if the class is constructed with one.

> Rewriting as lang3 but still using StringBuffer (synchronized) looks like a missed opportunity. Please use StringBuilder.
> Suggest audit for uses of StringBuffer in lang3 overall. No cause for it.
