That patch is in OpenJDK:

ecj is currently the only supported method for doing a build without
--disable-bootstrap, but that may change in the future.
Note that a normal OpenJDK build requires a Sun-based implementation
of Java 6, due to dependence on com.sun classes and AWT classes that
are part of the 1.6 specification.  We do our best to get round this
for IcedTea bootstrapping, but that testing is based on ecj+gcj not
Apple's products.
