Re: [jetty-users] PathResource warn in 9.3
Tried a git pull and got only java changes in the last 5 days - still looks like a broken build -?

Thanks,
Bill

This is the code.


Maybe if you change line #133 from

LOG.warn("bad alias ({}) for {}", e.getClass().getName(), e.getMessage());

to

LOG.warn("bad alias [" + path + "]", e);

we can get a better stacktrace (and path indication) to know what's going on.

It seems this is the first case of this warning on the web:

2015-07-02 13:16:57.019:WARN:oejur.PathResource:qtp1963387170-179: bad alias (java.lang.IllegalArgumentException) for null

I'm not sure what to make of it. It is associated with a stutter
in the user experience of loading pictures.

I have web page _javascript_ calling a servlet running under jetty
when the user clicks a 'next image' button. The servlet returns
an image file name, and the _javascript_ loads the file via jetty
http, following a soft link ROOT/images->[...]. There is only one
user doing one thing at a time.

I am getting these warnings singly when operation seems ok, and in
clusters when the user hasn't clicked 'next image' for a while. In that
case on the browser side, in conjunction with a cluster of these
warnings, I see several images flip by in less than a second. So
images are being loaded. I need to figure out how to debug from the
_javascript_ side and dig into the jetty source, but since PathResource
appears to be new, it seems this could be of interest.

Setup:

cd /opt/jetty-distribution-9.3.0.v20150612
java -jar start.jar \
    jetty.home=/opt/jetty-distribution-9.3.0.v20150612 \
    jetty.base=[...]/jetty-base

> egrep -v '^#' [...]/jetty-base/start.ini|awk 'NF > 0'

--module=http
