Looks like there is a bootstrap cycle initializing this lambda in ClassBuilder: https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/lang/classfile/ClassBuilder.java#L202

I'm not sure, but it looks like the PPC VM might be passing args to the bootstrap method differently, which triggers adapting code in BootstrapMethodInvoker::pushMePullYou - this might be enough to start this cycle.
