Linux start script requires java 1.5 though webgoat is compiled with java 1.6

[GoogleCodeExporter]

I discovered some problems with the 5.2 Release of WebGoat. I'm using the
Sun JDK in version jdk1.5.0_16 under linux with a x86 machine. When I
try to start WebGoat of the "standard" release, the Tomcat complains
about a "java.lang.UnsupportedClassVersionError:" error while deploying
the *.war file. This sounds to me like I should use a newer version of Java.
A look in the manifest.mf file WebGoat.war indicates that the 5.2
Release is compiled with java 1.6
However the startscript asks me to use Java 1.5 ("The JVM in $JAVA_HOME
isn't version 1.5.")

Bruce was kind enough to confirm the bug in the linux start-script (see
WebGoat-Mailinglist)

WebGoat-5.2$ sh webgoat.sh start8080

This also applies to Mac OS X, however it's a quick fix.

Eric, what is the fix for OS X ? I am running version 10.4, and seems like java 
1.6 is available only for 10.5 
onwards. I see the same error, is upgrading versions the only solution ?
