How exactly are you compiling? HashTree is part of src/jorphan and you should compile that submodule.
It's also unclear to me how are you trying to fix #53277. The problems doesn't seem to be with HashTree per-se but with the bad architecture of the calling code which adds "equal" elements. --emi On Fri, Jul 14, 2017 at 11:20 PM, Mareena Fernando <mareena....@gmail.com> wrote: > Hello, > > The issue description mentioned that issue is in "HashTree class".
