>Description:
I added license support to www/tomcat55 in ports/149848

Once this was added, I was able to install www/tomcat55 and the license handling achieved. 

One item I did come across, though, was since tomcat55 required diablo-jdk which also has a license, a continuous loop had occurred during installation of these two packages at the same time.

If I installed diablo-jdk first, and then installed tomcat55 there was no issue.

I am not very familiar with the pkg_* tool code, but I suspect that there may be an issue in handling more than one pkg in a dependency installation where more than one package requires a license acceptance agreement.
>How-To-Repeat:
Apply latest patch from ports/149848 to www/tomcat55
Do a pkg_add of diablo-jdk and tomcat55 at the same time.

I had done a Tinderbox Build and did a pkg_add -r tomcat (pointing it to the build environment)
