Improve CDS performance for custom class loaders

    Details

      generic

      Description

      There is a performance issue with CDS that is related to get jar entry of a class:
         To load shared class from CDS, first class file stream is read from jar file, then load the class with the stream. In vm, the stream is used to calculate file size and crc32 which are used to compare with the counter parts stored in CDS. Maybe we can find a way to make the process more efficient.
