public class StringBufferPool extends Object
This class pools string buffers, since they are reused so often. String buffers are good candidates for pooling, because of their supporting character arrays.

    // done before the instance is freed.
    // Fix attributed to Peter Speck <speck@ruc.dk>.
    sb.setLength(0);
    m_stringBufPool.freeInstance(sb);
