commit 0f7f2c757f779fd24509dbbdee7795bf6a541776
Author: Liam Miller-Cushon <cus...@google.com>

    Avoid referring to `PluginBuilderAttribute.class` in `PluginProcessor` 
(#4041)
    
    This makes it easier to build `PluginProcessor` by itself
    separately from the rest of `log4j-core`, and then include
    that processor when building the rest of core, instead of
    having to compile all of core twice.
