During the startup of a webapp I get really lots of these errors:

09:02:08,652 WARN  [ClassLoaderManager] Unexpected error during load of:com.foo.bar.MyTable: java.lang.VerifyError: class com.foo.bar.MyTable overrides final method getCellRenderer.(II)Ljavax/swing/table/TableCellRenderer;

The class MyTable extends from FoobarTable and FoobarTable extends from JTable... I'm little bit confused about the error message, because
I've got two getCellRenderer-methods. One of them overrides these one in JTable, the other one is private in both classes (MyTable and FoobarTable).
But no one of them is final.

Looks like:

public class FoobarTable  extends JTable {
@Override
public TableCellRenderer getCellRenderer(int row, int column) { ... }
private TableCellRenderer getCellRenderer(Class x){ ... }
} 

public class MyTable extends FoobarTable {
@Override
public TableCellRenderer getCellRenderer(int row, int column) { ... }
private TableCellRenderer getCellRenderer(Class x){ ... }
}
