You're right, doPrivileged() is a more straight-forward approach than 'sealed' variable. Since this might only be considered for inclusion in JDK9 when lambdas are already a tried technology, how do you feel about using them for platform code like logging?

I'm in favor of more platform code using lambda when appropriate. logging is a module separated from the base module in Jigsaw. I don't see any issue with that while the only thing is that when we backport it to 8u, the backport would be different - not an issue either.
I'm less sure on this about this (or rather just concerned there might be code paths that lead to recursive initialization issues when linking call sites). I see there are still cases where String.format is used when generating proxy classes and that will trigger the loading of locale-specific service providers. There is also exception handling in the proxy class dumping code that use the PlatformLogger. It might not be an issue with this specific patch as the compiler will (I think) generate the lambda method but just a general worry about anything that might run early in the startup.
