# Perform a mostly normal build.
# Since this test imports 'dalvik.annotation.optimization.FastNative' (and CriticalNative),
# we do a bit of trickery to allow the annotations to be used at javac-compile time,
# but remove them afterwards so it doesn't end up in the dex file.
#
# This enables the test to compile with vanilla RI javac and work on either ART or RI.
