JDK 1.7 error in autogen.sh

Hi all,
I have an i5 with 8GB ram PC running Fedora 16, it has OpenJDK 1.7
pre-installed in the box. When I am issuing the command: ./autogen.sh
--with-num-cpus=2, I hit the following error:

checking for java... /usr/bin/java
checking the installed JDK... checked (JDK 1.7.0_b147-icedtea)
checking for target Java bytecode version... 1.7
configure: error: 1.7 is not a supported Java bytecode version!
Error running configure at ./autogen.sh line 157.

May I know how this problem could be resolve?

THanks @!
