I don't think you should remove lines 228-232. These methods are called by
methods of CertificateFactory that take InputStream (which may contain a stream
of security data) and they are designed such that they try to read one
Certificate, CRL, or CertPath from the InputStream and leave the InputStream
ready to parse the next structure instead of consuming all of the bytes. Thus
they check if the InputStream supports mark in order to try to preserve that
behavior. If mark is not supported, then it's ok to use
InputStream.readAllBytes, otherwise, leave the stream as-is.
