Invalid Java 1.5 version?

[damonrand]

Hi,
   Starting up the alresco war under Tomcat 5.0.28 I am getting..

C:\java\Tomcat50\work\Catalina\localhost\alfresco\org\apache\jsp\index_jsp.java:7: cannot access java.lang.Object
bad class file: C:\java\jdk1.5.0_04\jre\lib\rt.jar(java/lang/Object.class)
class file has wrong version 49.0, should be 48.0

Is it telling me I can't run alresco on anything except jdk 1.5.0_03?

Regards,
Damon.

Upgraded to Tomcat 5.5.12 and the error went away!
