Bug 162281 Better parsing of BIRT_VIEWER_LOG_LEVEL parameter
java.util.logging.Level supplies a parse(String) method which parses log levels. Using this method is superior to the parsing used in ReportEngineServlet for the following reasons: - the level "ALL" is not recognized - one gets a proper exception if the level ins not recognized - a lot less code. I'll attach a patch for this.

outputStream.write( buf.toString( ).getBytes(
							ParameterAccessor.UTF_8_ENCODE ) );

						String value = null;
						try
						{
							value = cvsConvertor( (String) DataTypeUtil
									.convert( iData.getValue( columnNames[0] ),
											DataType.STRING_TYPE ) );
						}
						catch ( Exception e )
						{
							
						}
						if ( value != null )
						{
							buf.append( value );
						}
						for ( int i = 1; i < columnNames.length; i++ )
						{
							buf.append( ',' );
							try
							{
								value = cvsConvertor( (String) DataTypeUtil
										.convert( iData
												.getValue( columnNames[i] ),
												DataType.STRING_TYPE ) );
