What Java library for manipulating MS PowerPoint file?

I'm finding a PowerPoint library to copy, insert, delete, update and etc& slides of PowerPoint file. But I don't know what the best is. I tried use POI3.2 but its still have many bugs. I tried latest ASPOSE.Slide for java, it seem good library. But when I add Effect into slide, ASPOSE clone slide just work with entrance Effect type and lose Effect with the other.
My question: Is ASPOSE the best for me? (If no) What library should I choose?

Another question: Have a PowerPoint java library support .pptx(PowerPoint 2007) currently?

Many Thanks!

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am using Aspose PPT library for quite a time and I haven't been able to find any better so far. As for the pptx support - everything, but OLE manipulation should be supported (and OLE support is soon to come).
