[GitHub] [cxf] reta opened a new pull request #748: [WIP] CXF-8422: Unclosed input streams after using org.apache.cxf.tools.wsdlto.WSDLToJava (targeting StAX's XMLStreamReader)
reta opened a new pull request #748:
URL: https://github.com/apache/cxf/pull/748
```
/**
*<p>
* Note: as per StAX 1.0 specs, this method does NOT close the underlying
* input reader. That is, unless the new StAX2 property
* {@link org.codehaus.stax2.XMLInputFactory2#P_AUTO_CLOSE_INPUT} is
* set to true.
*/
@Override
public void close() throws XMLStreamException
```
But it still unclear why the file handle is not freed up.

Review comment:
That is correct (unless typecasted) but the value here is in how `AutoCloseableXMLStreamReader` defines `close` method: closing the reader and input stream. In my initial attempt, the `AutoCloseableXMLStreamReader` was promoted to return value (covering try-with-resources) but the consequences of closing the `InputSource` streams all the time are not clear to me. It could break things easily.

@coheigea @amarkevich mind taking a look guys? one more resource leak in certain circumstances in case of `XMLStreamReader` usage

Review comment:
AutoCloseable wont close source stream because returning XMLStreamReader cant be defined inside try-with-resources block
