Convert akka ByteString to Java InputStream?

Question

In scala, how can an akka.util.ByteString be converted to a java.io.InputStream ?

I tried the following:

val byteStringToInputStream : ByteString => InputStream = 
  byteStr => new ByteArrayInputStream(byteStr.asByteBuffer.array()))

But this results in an Exception being thrown

java.nio.ReadOnlyBufferException at java.nio.ByteBuffer.array(ByteBuffer.java:996)

Thank you in advance for your consideration and response.

Answer 1

var byteArray = byteString.toArray()
var inputStream = new ByteArrayInputStream(byteArray)

PS not a Scala developer (but a Java one). Hope I got it right with syntax.
