#

# The javac supplied with the LANGTOOLS_DIST should be used to build the

#   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.

#   (They should be the same). Re-using this built jdk as the ALT_BOOTDIR

#   jdk will be the only way and the recommeneded way to verify the built jdk

#   can bootstrap itself.

#

# The javac options supplied to the boot javac is limited. This compiler

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

#   class files that end up in the classes directory.
