[Red5] WAR version and java 1.5

[vlado]

I tried to build latest version of red5 from trunk with java 1.5 option 
in build.properties ( java.target_version=1.5  ). War file was created 
succesfully, but doesn't work. For example when I tried port_tester 
application, none port was tested successfully.

Then I download war file *red5*-0.6*rc3*-*java5*.war and the same 
problem occur. It's impossible to establish connection to red5.

Then I changed  java.target_version=1.6  and everithing works fine.

How to solve this problem?

Thanks!
