163 # LANGTOOLS_DIST javac should not be run during this jdk build and indeed

168 # the build. If the built jdk needs to be verified that it can build this
169 # same jdk, then it should be supplied to the build process as the ALT_BOOTDIR
170 # jdk, and this resulting built jdk should be compared to the first one.
171 # (They should be the same). Re-using this built jdk as the ALT_BOOTDIR
172 # jdk will be the only way and the recommeneded way to verify the built jdk
173 # can bootstrap itself.

177 # should only be used to build the 'make/tools' sources, which are not
178 # class files that end up in the classes directory.
