    Description

      TemporaryClob doesn't save the known length of the Clob in all situations.
      The following places in the code should be improved (some easier than others):
      a) TemporaryClob(String,ConChild)
      b) copyClobContent(InternalClob,long) (non-static)
      c) copyClobContent(InternalClob) (non-static)

      There might be additional places to fix too.
