Hi Nemoers. For the past couple of days, I'm addressing build flakiness issues for the master branch. It's hard to reproduce reliably, but the recent CI records [1-3] clearly shows we have a problem. I think it's not a Java 11 issue. Instead, I'm guessing an internal lockup lies behind the test failures. And it's not a compile-time error. Thus the issue Gon encountered while validating the RC4 should be addressed separately. Anyway, I'm investigating. Any hands for helping are more than welcome. Thanks! Jangho Seo
