I’ve investigated into the issue, and have succeeded to solve some problems by upgrading the versions of multiple java libraries. I’ve nevertheless faced a number of issues while upgrading the Beam version, and I’m trying to provide a fix ASAP 😀. I’ll file a PR as soon as I’m done :) hold tight!
P.S. I’ll also look into the ITCase issue that arises while compiling Nemo using multiple threads. - Wonook > On 31 Jan 2020, at 9:08 AM, Byung-Gon Chun <bgc...@gmail.com> wrote: > > Wonook, > > Any update on the jdk 1.11 issue? > > Thanks. > -Gon > > On Thu, Jan 23, 2020 at 7:59 AM Byung-Gon Chun <bgc...@gmail.com> wrote: > >> Hi Nemoers, >> >> It would be good to take a look at the problems Markus reported for the >> release. >> >> -Gon >> >> >> On Thu, Jan 23, 2020 at 6:16 AM Markus Weimer <wei...@apache.org> wrote: >> >>> Thanks for the insight.
