Bertrand Delacretaz commented on FELIX-961:
-------------------------------------------
I have seen similar problems when working on the Sling jcrinstall module,
framework seems to hang but is really only spending *lots* of time in the
R4SearchPolicyCore.findConsistentClassSpace() method.
Looks like my problem is more likely to happen with JDK 1.6 than with JDK 1.5:
the test scenario below always passes with 1.5 but "hangs" almost every time
with 1.6 (macosx, java versions "1.6.0-dp" and "1.5.0_16").
Note that I'm still running V1.0.4 of the Felix framework for those tests, so
not sure if it's the same problem.
Here's my test scenario FWIW.
Uses the Felix webconsole mounted at /system/console.
1. Install about 80 bundles (can't share those, sorry) via the console, using a
loop of CURL commands like
curl -F action=install -fbundlefi...@$f
http://admin:ad...@localhost:4502/system/console/bundles
2. Try to start all bundles using a loop of CURL commands like
curl -d action=start http://admin:ad...@localhost:4502/system/console/bundles/N
with N ranging from 20 (the number of bundles installed before 1.) to 150
With JDK 1.6, step 2. very often hangs when the first bundle is started (HTTP
response does not come), and jconsole shows the SCR Actor thread spending all
its time inside R4SearchPolicyCore.findConsistentClassSpace()
> 100% CPU looping inside uses calculation

> While investigating a problem report against pax-runner
> (http://article.gmane.org/gmane.comp.java.ops4j.general/6778) I found it was
> actually caused by a 100% CPU loop inside the "uses" calculation code. In
> Felix 1.4.1 this was stopping the shell bundle from activating, hence the
> lack of console. Using the trunk build I can get a console, but the looping
> still occurs with the testcase.
