That code won't be used if you do ServletContext.getResourceAsStream.
Also, the code in StandardClassLoader.findLoadedResource actually is :
protected InputStream findLoadedResource(String name) {
return (null); // FIXME - findLoadedResource()
}
In the new WebappClassLoader, it actually does some caching :
protected InputStream findLoadedResource(String name) {
ResourceEntry entry = (ResourceEntry) resourceEntries.get(name);
if (entry != null) {
if (entry.binaryContent != null)
return new ByteArrayInputStream(entry.binaryContent);
}
return (null);
}
but it does create a stream each time.
For the ServletContext, the thing creating the stream is the directory context
(FileDirContext), and it also does create a new stream each time.
