Wie kann das Problem behoben werden:

„Avoid the exception, you need to specify value 3 for the global property „db2.jcc.charsetDecoderEncoder“. By this way, JCC converts invalid characters to NULL instead of throwing exceptions, using „java.nio.charset.CodingErrorAction.REPLACE“ in case of error.  You can add following line into your Java property file if you already have one:     db2.jcc.charsetDecoderEncoder=3 or     specify „-Ddb2.jcc.charsetDecoderEncoder=3″ on Java command line. “
