How to remove an order entry？

code:

ModuleRootManager moduleRootManager = ModuleRootManager.getInstance(module);
OrderEntry[] orderEntries = moduleRootManager.getOrderEntries();
ModifiableRootModel modifiableRootModel = moduleRootManager.getModifiableModel();
LibraryTable moduleLibraryTable = modifiableRootModel.getModuleLibraryTable();
for (OrderEntry orderEntry : orderEntries) {
    if (!orderEntry.isValid()) { 
       modifiableRootModel.removeOrderEntry(orderEntry);
    }
}
modifiableRootModel.commit();

but I got an exception:
