明明已经释放连接池了，还是提示错误。请大家帮忙看看阿
PageQuery pageQuery = null;
  try {
  pageQuery = DBOperators.createPageQuery("AAA");
  if (opFlag.equals("insert")) 
  {
  sql = "******************************************";
  if (!pageQuery.simpleUpdate(sql)) {
  outFlag = "0";
  }
  } else if (opFlag.equals("update")) {
  sql = "******************************************";
  pageQuery.addBatchSql(sql);
  pageQuery.exeBatchSql();
  } else if (opFlag.equals("delete")) {
  sql = "**************************************";
  pageQuery.addBatchSql(sql);
  pageQuery.exeBatchSql();
  } else {
  }
  pageQuery.getData(mainFields, mainTable, mainStrConditions,mainPageSize);
  mainPageCount = pageQuery.getPageCount();
  mainCurrentPage = ((mainCurrentPage > mainPageCount)? mainPageCount : mainCurrentPage);
  vct = pageQuery.dividePage(mainCurrentPage);

  if (detailQuery.equals("true")) {
  sql = "***************************************************";
  ResultSet mainRS = pageQuery.getData(sql);
  }
   
  } catch (Exception e) {
  e.printStackTrace();
  }
  finally
  {
  Debug.println("*********************王涛连接池关闭,finally****************************");
  pageQuery.close();
  }




后台提示错误

------解决方案--------------------
pageQuery.close(); 
代码贴上来
------解决方案--------------------
某一连接在调用close之前被垃圾收集器回收，返回连接池，导致泄漏，再查查吧
