Re: Problem when rebooting....
Hi Bjorn,
I'm looking into the issue(I had been longing to contribute to community
and I see some opportunity to start doing so here. Hope my effort will be
welcomed!:) )
I'm looking at the code base in trunk. Here is the method where
localhost-startstop thread is busy:
protected void processAnnotationsFile(File file, WebXml fragment, //line
1963
boolean handlesTypesOnly) {
if (file.isDirectory()) {
// Returns null if directory is not readable
String[] dirs = file.list();//line 1968
if (dirs != null) {
for (String dir : dirs) {
processAnnotationsFile(//line 1971
new File(file,dir), fragment, handlesTypesOnly);
}
}
} else if (file.canRead() file.getName().endsWith(.class)) {
try (FileInputStream fis = new FileInputStream(file)) {
processAnnotationsStream(fis, fragment, handlesTypesOnly);
} catch (IOException e) {
log.error(sm.getString(contextConfig.inputStreamFile,
file.getAbsolutePath()),e);
} catch (ClassFormatException e) {
log.error(sm.getString(contextConfig.inputStreamFile,
file.getAbsolutePath()),e);
}
}
}
As you can see and as konstantin said, the thread is busy walking over
directories listed in web-fragements. Here it is from where it is being
called:
protected void processAnnotations(SetWebXml fragments,
boolean handlesTypesOnly) {
for(WebXml fragment : fragments) {
// Only need to scan for @HandlesTypes matches if any of the
// following are true:
// - it has already been determined only @HandlesTypes is
required
// (e.g. main web.xml has metadata-complete=true
// - this fragment is for a container JAR (Servlet 3.1 section
8.1)
// - this fragment has metadata-complete=true
boolean htOnly = handlesTypesOnly || !fragment.getWebappJar() ||
fragment.isMetadataComplete();
WebXml annotations = new WebXml();
// no impact on distributable
annotations.setDistributable(true);
URL url = fragment.getURL();
processAnnotationsUrl(url, annotations, htOnly);// This in turn
calls processAnnotationsFile
SetWebXml set = new HashSet();
set.add(annotations);
// Merge annotations into fragment - fragment takes priority
fragment.merge(set);
}
}
I'will let you know, as soon as I come to some concrete understanding.
Meanwhile you can take a look at various web-fragments in your
web-application.

Ameer Mawia,
