I have a logging properties file which contains these two lines:
handlers=java.util.logging.ConsoleHandler my.Handler
java.util.logging.ConsoleHandler.formatter=my.Formatter
System classloader initialization fails with the appended exception output. In
both cases here, it appears that the system is unable to initialize the
classloader because it cannot find classes which will not be available until
after the classloader initializes. I'd guess the right fix is to delay
initializing the logger until later in the classloader initialization process,
but I haven't dived very deeply into the code to be sure.
