             Summary: ByteBuffer to String conversion uses buffer capacity not limit
                 Key: CAMEL-7241
                 URL: https://issues.apache.org/jira/browse/CAMEL-7241
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.12.3
            Reporter: Aaron Whiteside


Camel's conversion logic for ByteBuffer's to String's has a bug where camel uses a ByteBuffers capacity() instead of it's limit().

If you allocate a large byte buffer and only partially fill it with data, and use camel to convert this into a string, camel tries to convert all the bytes, even the non-used ones.

This unit test reproduces this bug.

{code}
    @Test
    public void testByteBufferToStringConversion()
    {
        String str = "123456789";
        ByteBuffer buffer = ByteBuffer.allocate( 16 );
        buffer.put( str.getBytes() );

        Exchange exchange = new DefaultExchange( context() );
        exchange.getIn().setBody( buffer );
        assertEquals( str, exchange.getIn().getBody( String.class ) );
    }
{code}
