Cannot add table to docx create by Libreoffice

I created a template document using LibreOffice 3.5. If I open the document and try to add an empty table to it using the table factory:
TblFactory.createTable(3, 3, cellWidthTwips);
I get these log messages:
16:09:26,494 ERROR [main] PropertyResolver:1405 - Expected TableNormal to have <w:basedOn ??
16:21:02,390 WARN [main] MainDocumentPart:548 - TableGrid couldn't be activated!
If I use a debugger to change the 'result1' variable in PropertyResolver, the resulting docx file opens just fine In LibreOffice. It seems style.xml created by LibreOffice does not define a style called 'TableNormal'. Is the 'result1' variable really required? I don't know the docx-spec well enough to know if the check in the PropertyResolver is for the spec or the MS-Word implementation.
