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.
> ToStringBuilder should use StringBuilder

> Components: lang.*
> Affects Versions: 3.1
> Reporter: Shevek

> 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.
