Unfortunately I don't have a system to reproduce this on. Looking at
the documentation of /RTC1[1] it's pointed out that it should only be
enabled for debug builds. This suggests we need to add this flag only
for slowdebug builds. It's being added here:
http://hg.openjdk.java.net/jdk-updates/jdk11u/file/4675b75ee535/make/lib/Lib-jdk.hotspot.agent.gmk#l47

That is, we no longer can add that flag unconditionally. I've filed this bug:
https://bugs.openjdk.java.net/browse/JDK-8212110

I'll see if I can come up with a patch which you can test.

Thanks,
Severin
