Hi @seanjmullan, @mcpowers, 
Corresponding to the JBS issue, this bug affects also older releases. Shoudn't it be backported, given that the fix is rather simple? It increases heap usage slightly, but it seems unlikely that this has a noticeable effect. If you agree, I would address this.
Thanks, Goetz.
