Please review this small fix to property cleaning. We normally build on
Solaris (11.1) machines with gnu tools installed, including gnu sed so
this has not affected official Oracle builds or JPRT. However, we cannot
rely on gnu sed always being present so the build should be correct even
with Solaris sed. The problem in this case is that Solaris sed ignores
the last input line unless it is terminated by a newline character. The
fix is to add an empty echo after the cat. The sed expression is already
filtering out empty lines so the final output will not be changed.
I have verified that the affected lines no longer disappears when using
diff --git a/make/common/JavaCompilation.gmk
