Compiling java icedtea for openjdk 7 with openjdk 6


Im running a gentoo machine and setting up java on my machine and I am having a bit of trouble getting some information on whether I can bootstrap openjdk7 with a jdk6 compiler. I keep hitting an error and IDK if it is due to some sort of misconfiguration.

Code:
../../../src/share/classes/java/lang/management/PlatformComponent.java:42: error: Util is not public in sun.management; cannot be accessed from outside package
import sun.management.Util;
                     ^

                        result = Util.newObjectName(LOGGING_MXBEAN_NAME);
                                     ^

You could try it with the latest Oracle-JDK, too. (It's 8u40 in this moment.)

Yeah I know I could do that and I can use a bin distributed package opened 7 from my distro and it compiles fine. But I use a source base distribution and I wanted to be able to compile newer forms of Java with older compilers so I can skip a bin install
