On the 13th November 2006 Sun announced its decision to begin the process of open sourcing Java SE and ME under the GPL v.2. The decision was broadly welcomed, although Sun did lose two senior executives who cited the open source policy as their main reason for departing. Vice President and senior Fellow Graham Hamilton, who had helped create the JCP and led the Java SE team for a while, left within weeks of the announcement. More recently Larry Singer, Vice President of Global Information Systems Strategy, left and again cited Sun's open source strategy as a significant factor.
