Class jdk.internal.HotSpotIntrinsicCandidate not found - continuing with a stub.

I see this error compiling with 2.12.5 or 2.12.6 with -opt:inline -opt-inline-from:** with JDK 10.

Class jdk.internal.HotSpotIntrinsicCandidate not found - continuing with a stub.

It's okay with JDK 9.

2.12.4 also fails, but more messily:

If the problem isn't obvious, let me know and I will try to come up with a minimized example. Or at least an example.

[SethTisue]

looks like a variant of #10717

[SethTisue]

@aryairani is this fixed in Scala 2.12.7-bin-f2129b9, which is our current 2.12.7 release candidate? it's available via resolvers += "scala-integration" at "https://scala-ci.typesafe.com/artifactory/scala-integration/"

[SethTisue]

@aryairani I'll assume this got fixed in 2.12.7 unless you or someone lets us know differently

Sorry for the delay, we have been staying on JDK 9 since encountering this and I haven't had an opportunity to get set up with JDK 10 to try again.
