WAS 6.1 shows Java version 5, but its really 1.4

I have a strange problem.

I have configured our Websphere Application Server to run Java 5. Its a really old application that I have migrated from Java 4.

If I in the jsp page print

System.getProperty("java.version")
System.getProperty("java.specification.version")
System.getProperty("java.vm.name")

I get

Java version: 1.5.0
java.specification.version: 1.5
java.vm.name: IBM J9 VM

However, If I in the jsp change the code from List to List<Object> I get the following exception:

The type ArrayList is not generic; it cannot be parameterized with arguments <Object> JSPG0091E: An error occurred at line: 79 in the file: /jsp/archive/archiveoverview.jsp JSPG0093E: Generated servlet error from file: /jsp/archive/archiveoverview.jsp C:\SDP75\runtimes\base_v61\profiles\was61profile1\temp\CR122599Node01\server1\myifEAR\myif.war\jsp\archive\_archiveoverview.java : 199 : Syntax error, parameterized types are only available if source level is 5.0

How can this be???

The JVM used to run WebSphere Application Server is different from the compiler compliance level used to compile JSPs running within the server. See this technote: Using Java 5 language feature in a JSP targeting WebSphere Application Server v6.1.
