/**
 * This complex test checks the functionality of the properties "Finalized" and "Mandatory" of
 * the services <CODE>com.sun.star.document.FilterFactory</CODE> and
 * <CODE>com.sun.star.document.TypeDetection</CODE>.
 *
 * Each of theses services represent a container of <CODE>PropertyValue[]</CODE>.
 * The <CODE>PropertyValue[]</CODE> contains among others the properties called 
 * <CODE>Finalized</CODE> and <CODE>Mandatory</CODE>. If the property
 * <CODE>Finalized</CODE> is set to <CODE>true</CODE>, a filter can be removed
 * but will not be able to be changed.
 * If the property <CODE>Mandatory</CODE> is set to <CODE>true</CODE>, the filter
 * can not be removed.
 *
 * Every filter, which is registered to the office, will be tested. For every filter-test
 * a new instance of the mentioned services will be created. 

 * During the test the property <CODE>UIName</CODE>
 * will be changed and the service will be flushed. The test checks for expected exceptions: 
 * If the property <CODE>Finalized</CODE> equals
 * <CODE>true</CODE> the tests check if an <CODE>Exception</CODE> must be thrown.
 * The next step of the test is the removal of the filter was removed, than the service 
 * will be flushed. The test checks for expected exceptions: If the property
 * <CODE>Madantory</CODE> equals <CODE>true</CODE>, an <CODE>Exception</CODE> must
 * be thrown.
 * This test results <CODE>false</CODE> state if there is no filter available with:
 * <CODE>Finalized=true</CODE>
 * <CODE>Finalized=false</CODE>
 * <CODE>Mandatory=true</CODE>
 * <CODE>Mandatory=false</CODE>
