Problem moving to java 1.6.0_23

[marco turchi]

Dear All,
I have a strange error changing Java version.

I have this line of code:

RandomAccessSparseVector document = new
RandomAccessSparseVector(Integer.MAX_VALUE);

and it works properly using java jdk1.6.0_17, but when I change java to a
newer version jdk1.6.0_23, I get this mistake:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/mahout/math/function/IntDoubleProcedure

I check in the jar file of Mahout Math and this method is not present.

Please can you help me?

Thanks
Marco
