# ClassAnalyzer depends on the com.sun.tools.classfile API.
# The tool is compiled with the latest version of the classfile 
# library in the langtools repo to make sure that synchronized
# change is made if the classfile API is changed. 
#
# If langtools repo exists, build its own copy of the
# classfile library and use it for compile time and runtime.
# If not exist (the top level repo is not a forest), use 
# the built jdk tools that imports tools.jar from the latest
# promoted build.
#
# If the classfile API is changed but not yet in a promoted build,
# the build might fail and the tool would need the langtools repo
# to build in that case.
