Performance regression in BuiltinClassLoader?

[Eirik Bjørsnøs]

Alan,

I have been using "make images" all along. This
produces build/macosx-x86_64-server-release/jdk/modules with unpacked
modules.

I'm a bit confused since "make help" seems to indicate that "make jdk"
should create unpacked modules, while "make images" should perhaps not? Or
did I misunderstand?

Eirik.
