Description

1.line 140 code in DataMask

    public static DataMask build(DataMaskDescription mask,
    TypeDescription schema,
    MaskOverrides overrides) {
    Iterator<Provider> iterator = LOADER.iterator();
    LOG.info("hgs-"Thread.currentThread().getName()"--start........" +mask.getName());
    LOG.info("hgs--"Thread.currentThread().getName()"—start........");

140   while(iterator.hasNext())

{     LOG.info("hgs--"+Thread.currentThread().getName()+"--"+ iterator.next().getClass().getName());    }

    LOG.info("hgs-"Thread.currentThread().getName()"--end........");
    for(Provider provider: LOADER) {
    DataMask result = provider.build(mask, schema, overrides);
    if (result != null)

{     return result;     }

    }
    throw new IllegalArgumentException("Can't find data mask - " + mask);
    }
