Reversengineering java-files in Rose

It is imppossible for me to import the openehr java files in Rose, it mocks a lot about errors like below

12:01:10| Parser Error: near token < on line 43 occurred in File E:\openEhr.org\ref_kernel_java\TRUNK\src\java\org\openehr\am\archetype\constraintmodel\CMultipleAttribute.java

The error is in the line:

    public CMultipleAttribute(String path, String rmAttributeName,
                              Existence existence, Cardinality cardinality,
--> List<CObject> children) {

I guess this is a setting in Rose, or a stupid misunderstanding from me.

Can someone help me out.

I must say, I can read Java-code wel, but I do not know all the nitty gritty details about all its syntaxes

Thanks
