Hi Pavel,
I bet it's due to the pax-url-aether: it waits the mvn resolution
timeout (even if it's not a mvn URL) before "falling" back to http or
file URL.
Let me check if we can improve that.

Hello,
I'm a new user of Karaf and recently I've upgraded from Karaf 2.2.8 to 3.0.0
(running with JDK jdk1.7.0_17 on Windows).
I've noticed that in the new Karaf there's a ~ 30 seconds delay (timeout)
when installing features using file: or http: protocol, even though using
mvn: protocol works fast.
To make a clean test, I've unzipped Karaf 3.0.0 and then added the following
feature repo:
<features xmlns="http://karaf.apache.org/xmlns/features/v1.2.0"; name="test">
<feature name="testFeature" version="1.0.0">
<bundle>mvn:org.apache.servicemix.nmr/org.apache.servicemix.nmr.api/1.0.0-m2</bundle>
</feature>
</features>
installing the feature using mvn: protocol is fast.
however, both:
file:/d:/temp/org.apache.servicemix.nmr.api-1.0.0-m2.jar
and
http://repo1.maven.org/maven2/org/apache/servicemix/nmr/org.apache.servicemix.nmr.api/1.0.0-m2/org.apache.servicemix.nmr.api-1.0.0-m2.jar
take the feature at least 30 seconds to install.
I've had a look at the BundleManager class'
(https://apache.googlesource.com/karaf/+/trunk/features/core/src/main/java/org/apache/karaf/features/internal/BundleManager.java),
private void waitForUrlHandler(String protocol) method, and saw a wait call
there:
urlHandlerTracker.waitForService(30000);
This could be the reason of the delay for the file: and http: protocols.
Is there a way to avoid this delay (as with the mvn: protocol)? We're using
the install feature functionality in our application on a regular basis, so
having this timeout can seriously hinder overall performance.
This was not an issue with the older Karaf 2.2.8.
Thanks for you help!
