	} finally {
	if (out != null) {
	try {
	out.close();
	} catch (IOException e) {
	log.warn("out close failed...", e);
	}
	}

analysis and explanation:
This method allocates and uses an auto closeable resource. However, it manually closes the resource in a finally block. While this is correct management, it doesn't rely on the idiomatic way available to JDK 7 and above, allows for possible subtle problems, and complicates the reading of code by developers expecting the use of try-with-resources.

Describe the solution you'd like

Change to use try-with-resources to manage resources.

Is this issue still alive? It seems nobody has been working long time on it. If so I would like to pick it up.
