Question

Answer 1

Instead of using StringWriter/StringBufferInputStream, write your original InputStream to a ByteArrayOutputStream. Once you've finished reading from the original InputStream, pass the byte array returned from ByteArrayOutputStream.toByteArray to a ByteArrayInputStream. Use this InputStream as the InputStream of choice for passing around other things that need to read from it.

Essentially, all you'd be doing here is storing the contents of the original InputStream into a byte[] cache in memory as you tried to do originally with StringWriter/StringBufferInputStream.
