The statement follows a recent Wall Street Journal editorial that speculated about the latter possibility. The editorial was based on a letter sent to Ellison on Sept. 15 by SAP CEO Léo Apotheker, which consisted of the following statement, according to the Journal:

"As you know, we have significant concerns about Oracle's proposed takeover of Sun. We renew our invitation to meet to attempt to resolve our concerns and other open issues between our companies. Please let us know if and when you would like to meet."

The Journal noted that "other issues" between the two companies include an ongoing intellectual property lawsuit Oracle filed against SAP in connection with TomorrowNow, a now-shuttered subsidiary of SAP that provided third-party support for Oracle applications.

SAP "strongly rejects" the editorial's "misleading speculation," Wednesday's statement said, reiterating remarks by an SAP spokesman earlier this week.

Instead, SAP has "concerns about customer choice in the database market and the future open licensing of Java," and first contacted Oracle and Sun about the matter "as far back as the end of July 2009."
