Yeah, that seems tricky issue here.   I haven't had any time to

It was definitely a JRE bug. They were inserted an invalid inflater back 
into their infater pool. This appears to be the same issue looking at 
the original stack trace below. This is not a Felix issue. Perhaps there 
is some workaround we could devise, but I'm not sure what.

For felix 3.0.6, i suppose there has been some changes in the boot
loader delegation mechanism, but not sure when those have been
introduced.   Maybe checking with karaf trunk which uses pax-web 0.8.0
and felix 3.0.6 to make sure that this does not happen anymore.

For karaf 2.1.1 release under vote, i suppose we should add a note on
the release notes at least or switch back to 0.7.2 in 2.1.2 if needed.
  Not sure really what's the best way yet, but this should be discussed
on karaf dev list rather than here.

Guillaume,

I switched back to pax-web 0.7.3 and verified that I get the
NullPointerException. I then switched to Equinox - it works with no
problems. I use the Equinox version that comes with Karaf 2.1.0.

I then tried to switch from Felix 3.0.2 (which comes with Karaf 2.1.0) to
Felix 3.0.6 but I haven't managed to do that successfully.

All I did was to change the karaf.framework.felix in Karaf's
config.properties to Felix 3.0.6 which I also downloaded and put in the
right place under "system".

Karaf starts with no problems, however, I cannot login from the Webconsole
(I use the default karaf/karaf). In the log I get:

What else do I have to do to switch to Felix 3.0.6?

So, it seems like Equinox does not have any problems with pax-web 0.7.3.
That certainly indicates some problem in Felix. However, Richard S Hall
investigated this in FELIX-1032 and came to the conclusion that it's not a
Felix bug. What do you think?

2010/11/11 Bengt Rodehav<[email protected]>


I'll give Equinox and Felix 3.0.6 a try.

Thanks for the tip,

/Bengt

2010/11/10 Guillaume Nodet<[email protected]>

Have you tried to reproduce the issue using Equinox ?  Also maybe

upgrading to Felix Framework 3.0.6 ?
I've also seen those issues but haven't had any time to investigate so
far.

I get the same problem.

I use Karaf 2.1 which relies on pax-web 0.7.3. I've tried pax-web 0.8.0
which was just released but it doesn't work either. I seem to get rid of
this problem when reverting to pax-web 0.7.2 like you suggested to Irad.
However I had to patch the feature file that comes with Karaf 2.1 to do
this.

Does anyone know if someone is working to fix this? Is it reported? I'm

not

sure if it should be reported to the Jetty people, Ops4j or perhaps

Felix or

Karaf.

I would really like to upgrade to pax-web 0.8.0 (with Jetty 7) but right

now

it seems like I'm stuck at 0.7.2...

Does anyone know if a fix is in the works somewhere?

/Bengt

2010/11/2 Allen Lau<[email protected]>


There is a problem with newer Jetty versions running inside of Felix

that

causes this problem.   Don't remember the thread that pinpoints the

exact

issue.  Reverting back to PAX-WEB 0.7.2 solves the issue.   Give that a
try.

Hi,

Was wondering if anyone can help.



I am getting the below set of behaviours after trying to install or
uninstall a feature with  Karaf 2.1.0 web console on a spawned server
instance (not the main karaf server).

1.      I try to install / uninstall a feature

2.      At first The web console does not respond and seems stuck

3.      If I wait with no refresh, I sometimes see an empty features
screen (Feature information: 0 features in total - all 0 features
active.)

4.      But after a refresh the feature seems installed.

5.      Sometimes the web console seems to have completely died and I
cannot access any of the tabs

6.      Sometimes I get the following AJAX Error pop-up screen:

a.      The request failed:

b.    HTTP ERROR 405

c.  Problem accessing /system/console/features. Reason:

d.  HTTP method POST is not supported by this URL

e.
