I did follow those instructions, but there has been an update to the OpenJDK., and I am building one version of the AOSP behind the current. So roll the JDK back.

I applied the above fix, and got this error:

upon receiving that error I removed the last line in the flags and made my HOST_x86_common.mk file look the same as it does here:
