# This is always required on a Mac, because the system langtools classes
# are always on the main class path; in addition, it may be required on
# standard versions of JDK (i.e. using rt.jar and tools.jar) because some

# Assume that the jar file being invoked lists all the necessary langtools
# jar files in its Class-Path manifest entry, so there is no need to search
