The move was surprising, as Oracle and Apache have had a contentious relationship over another open-source project, Java. Oracle subpoenaed Apache as part of its lawsuit against Google for violating Java patents in the Android mobile operating system. Oracle also blocked Apache's Project Harmony from getting a Java license, which resulted in Apache quitting the Java Community Process in protest. IBM relies heavily on OpenOffice and the ODF (Open Document Format) for its own Lotus Symphony office suite. The company, which had been lobbying for Oracle to spin off Open Office in the first place, immediately welcomed Oracle's decision. "We look forward to engaging with other community members to advance the technology beginning with our strong support of the incubation process for OpenOffice at Apache," said Kevin Cavanaugh, vice president of collaboration solutions at IBM.
