Thorsten Scherler commented on FOR-1079:
----------------------------------------
I did
ngrep forrest
ngrep dtd
as su but that did only return #.
However the exception:
...
java.net.UnknownHostException: forrest.apache.org
at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177)
Meaning we actually want to connect to forrest.apache.org.
...
at
sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:938)
at org.apache.xerces.impl.XMLEntityManager.setupCurrentEntity(Unknown
Source)
That is interesting! The method reads (sniped to the interesting parts):
/**
* This method uses the passed-in XMLInputSource to make
* fCurrentEntity usable for reading.
* @param name name of the entity (XML is it's the document entity)
* @param xmlInputSource the input source, with sufficient information
* to begin scanning characters.
* @param literal True if this entity is started within a
* literal value.
* @param isExternal whether this entity should be treated as an
internal or external entity.
* @throws IOException if anything can't be read
* XNIException If any parser-specific goes wrong.
* @return the encoding of the new entity or null if a character stream was
employed
*/
public String setupCurrentEntity(String name, XMLInputSource xmlInputSource,
boolean literal, boolean isExternal)
throws IOException, XNIException {
// get information
...
// create reader
InputStream stream = null;
Reader reader = xmlInputSource.getCharacterStream();
// First chance checking strict URI
String expandedSystemId = expandSystemId(literalSystemId, baseSystemId,
fStrictURI);
if (baseSystemId == null) {
baseSystemId = expandedSystemId;
}
if (reader == null) {
stream = xmlInputSource.getByteStream();
if (stream == null) {
URL location = new URL(expandedSystemId);
URLConnection connect = location.openConnection();
if (!(connect instanceof HttpURLConnection)) {
// NOTE thorsten:
// The following line will produce the error
stream = connect.getInputStream();
}
else {
...
The above code seems to be responsible to produce the exception.
at org.apache.xerces.impl.XMLEntityManager.startEntity(Unknown Source)
at org.apache.xerces.impl.XMLEntityManager.startDTDEntity(Unknown
Source)
seems that it is related to the DTD entities.
...
at
org.apache.tools.ant.taskdefs.optional.XMLValidateTask.doValidate(XMLValidateTask.java:539)
and it related to the validate task.
That is why setting
forrest.validate=false
is an ugly but working workaround.

> If you remove the DNS server entries from your OS forrest cannot validate

> sudo vi /etc/resolv.conf

> try "forrest" as usual on your project, it will fail like:
