Resolution: Fixed
Assignee: Edouard De Oliveira
> Initialise return ByteBuffer from PoolByteBufferAllokator with 0
> ----------------------------------------------------------------
>
> Key: DIRMINA-622
> URL: https://issues.apache.org/jira/browse/DIRMINA-622
> Project: MINA
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.1.7
> Reporter: Stefan Gmeiner
> Assignee: Edouard De Oliveira
> Priority: Trivial
> Fix For: 1.1.8
>
>
> A ByteBuffer returned by calling ByteBuffer.allocate() on a
> PooledByteBufferAllocator is not guarenteed to be initialised to 0 as it
> would be if a SimpleByteBufferAllocator was used.
> The java equivalent java.nio.ByteBuffers are always initialised with 0 hence
> the MINA variant should also follow this convention independent if
> PooledByteBufferAllocator was used or not.
>
> import org.apache.mina.common.ByteBuffer;
> public class PooledByteBufferTest {
> public static void main(String[] args) {
> ByteBuffer.setAllocator(new PooledByteBufferAllocator());
> ByteBuffer buffer1 = ByteBuffer.allocate(100);
> System.out.println("buffer1[0]=" + buffer1.getInt(0)); //
> prints 0
> buffer1.putInt(42);
> System.out.println("buffer1[0]=" + buffer1.getInt(0)); //
> prints 42
> buffer1.release();
> ByteBuffer buffer2 = ByteBuffer.allocate(100);
> System.out.println("buffer1[0]=" + buffer2.getInt(0)); //
> prints 42 instead of 0
> }
> }
