# The boot_cycle.sh script performs two complete image builds (no javadoc though....)+
−
# where the second build uses the first build as the boot jdk.+
−
#+
−
# This is useful to verify that the build is self hoisting and assists+
−
# in flushing out bugs. You can follow up with compare_objects.sh to check+
−
# that the two boot_cycle_?/images/j2sdk are identical. They should be.+
−
#+
−
# Usage:+
−
# Specify the configure arguments to boot_cycle.sh, for example:+
−
#+
−
#    sh common/bin/boot_cycle.sh --enable-debug --with-jvm-variants=server+
−
#+
−
# The same arguments will be used for both builds, except of course --with-boot-jdk+
−
# that will be adjusted to boot_cycle_1 for the second build.+
