IllegalArgumentException applying table filter

Hello,

using the table filter functionality we got the following exception:

java.lang.IllegalArgumentException: fromIndex(35) > toIndex(32)

at java.util.Arrays.rangeCheck(Arrays.java:1320)

at java.util.Arrays.fill(Arrays.java:2315)

at com.sap.tc.webdynpro.basesrvc.util.SparseList$InnerPage.shrinkToSize(SparseList.java:332)

at com.sap.tc.webdynpro.basesrvc.util.SparseList$InnerPage.shrinkToSize(SparseList.java:335)

at com.sap.tc.webdynpro.basesrvc.util.SparseList.setSize(SparseList.java:614)

....

The exception is raised only when there are more than 800 entries in the table.

We use the netweaver 7.1.

Some hints?

Regards,

Uwe
