Gap present between the choice and its drop down list in Jdk 7 build for a non resizable frame.

There is a large gap between the choice and its drop down list from Jdk 7 build onwards.
This happens only when the frame is not resizable.
This is reproducible in Solaris and linux.
I tested it with Solaris Sparc and Open Solaris, RHEL 5.
It works fine with Windows.

Steps to Reproduce:
1. Run the attached testcase(TestChoice.java) in jdk build 7 in Solaris and Linux.
2. Click on the Choice and see that there is a large gap between the Choice and its drop down list.
