RMTESToUTF8 does not work (Java SDK)

[mzl-financial-com]

The function RMTESToUTF8 does not work.

Function can be found in the class

https://github.com/Refinitiv/Real-Time-SDK/blob/master/Java/Eta/Core/src/main/java/com/refinitiv/eta/codec/RmtesDecoderImpl.java

The problem can be reproduced in the following unit test:

	@Test
	public void testRMTESToUTF8() {
		final byte[] test = new byte[] { (byte)0x1B, (byte)'%', (byte)'0', 'C', 'P', 'I' };
		
		final Buffer buffer = CodecFactory.createBuffer();
		buffer.data(ByteBuffer.wrap(test));
		
	    final RmtesDecoder rmtesDecoder = CodecFactory.createRmtesDecoder();
	    final RmtesCacheBuffer rmtesCacheBuffer = CodecFactory.createRmtesCacheBuffer(0, ByteBuffer.allocate(64), 64);
	    final RmtesBuffer rmtesBuffer = CodecFactory.createRmtesBuffer(0, ByteBuffer.allocate(64), 64);
	    
		int ret;
		
		ret = rmtesDecoder.RMTESApplyToCache(buffer, rmtesCacheBuffer);
		Assert.assertEquals(CodecReturnCodes.SUCCESS, ret);
		
		ret = rmtesDecoder.RMTESToUTF8(rmtesBuffer, rmtesCacheBuffer);
		Assert.assertEquals(CodecReturnCodes.SUCCESS, ret);
		
		final int decodedLength = rmtesBuffer.length();
		rmtesBuffer.byteData().limit(decodedLength);
		final byte[] target = new byte[decodedLength];
		rmtesBuffer.byteData().get(target, 0, decodedLength);
		
		Assert.assertEquals("CPI", new String(target));
	}

The error seems to be in the following lines:

                else
                    /* Just copy the data, since it's already encoded in UTF8 */
                {
                    if (outIterCount + 1 > rmtesBuffer.allocatedLength())
                        return CodecReturnCodes.BUFFER_TOO_SMALL;

                    rmtesBuffer.byteData().put(outIterCount++, rmtesBuffer.byteData().get(outIterCount));
                    inIterCount++;
                }

which copy from output to output buffer. Unlike the C implementation:

			else /* Just copy the data, since it's already encoded in UTF8 */
			{
				*outIter = *inIter;
				outIter++;
				inIter++;
			}

which copies from input to output buffer.
