Error writing Frame accumulator bytes since 5.27.0

[markus-raffling-skidata]

Describe the bug

With amqp-client java library version 5.27.0 the method writeToByteBuf in class com.rabbitmq.client.impl.Frame has a bug when writing the accumulator bytes in line 218

@Override
public void write(byte[] b) {
	buf.writeBytes(buf);
}

buf.writeBytes(buf);
should be changed to
buf.writeBytes(b);

The effect is that an invalid frame will be sent to the RabbitMQ server, example for channel open:
01 00 01 00 00 00 05 ce
instead of
01 00 01 00 00 00 05 00 14 00 0a 00 ce
and no channels can be opened anymore.

Note for reproduction:

java.io.ByteArrayOutputStream.writeTo(OutputStream) calls either method
write(byte[] b)
or method
write(byte[] b, int off, int len)
depending the current thread is virtual or not

public void writeTo(OutputStream out) throws IOException {
	if (Thread.currentThread().isVirtual()) {
		byte[] bytes;
		synchronized (this) {
			bytes = Arrays.copyOf(buf, count);
		}
		out.write(bytes);
	} else synchronized (this) {
		out.write(buf, 0, count);
	}
}

Reproduction steps

1. open a RabbitMQ connection with netty config and virtual thread
2. create a channel

Expected behavior

Channel should be created, accumulator bytes should be sent to RabbitMQ
