# may not even run with the ALT_BOOTDIR jdk because they may be a newer
# class file version that the ALT_BOOTDIR jdk doesn't understand.

# The important observation here is that the built jdk is NOT run during
# the build. If the built jdk needs to be verified that it can build this
# same jdk, then it should be supplied to the build process as the ALT_BOOTDIR
# jdk, and this resulting built jdk should be compared to the first one.

# jdk will be the only way and the recommeneded way to verify the built jdk
# can bootstrap itself.

# should only be used to build the 'make/tools' sources, which are not
