2.10.0-RC6 macro does not support large case class (throw ClassNotFoundException: scala.Tuple25)

[xuwei-k]

Play JSON Version (2.5.x / etc)

2.10.0-RC6

API (Scala / Java / Neither / Both)

Scala

Operating System

all

JDK

all

Library Dependencies

only play-json 2.10.0-RC6. see following build.sbt

Expected Behavior

derive Json type classes.
play-json 2.10.0-RC5 does not have this issue if set scalacOptions += "-Xmax-inlines:100" .

Actual Behavior

throw ClassNotFoundException

play-json/play-json/shared/src/main/scala-3/play/api/libs/json/QuotesHelper.scala

Line 163 in d841976

TypeRepr.typeConstructorOf(Class.forName(s"scala.Tuple${types.size}"))

Reproducible Test Case

build.sbt

libraryDependencies += "com.typesafe.play" %% "play-json" % "2.10.0-RC6"
