I am surprised that you are seeing an issue in 3.2.2 because the default in 3.2 is to delegate to the boot classpath first for all class loads (the default setting in 3.2 is org.osgi.framework.bootdelegation=*). The osgi.compatibility.bootdelegation option was added in 3.3 because we no longer default to org.osgi.framework.bootdelegation=*.
Be sure that the system property org.osgi.framework.bootdelegation=* in
your 3.2 environment.

Subject: Re: [equinox-dev] Bootdelegation question
We've come across a problem in which the osgi.compatibility.bootdelegation
property might work for us. We noticed that intermittently, we get a CNFE
from one of our bundle's start() methods when it tries to load one of our
own classes from a jar that is on the boot classpath (not a part of a
plugin). Is this a known issue and do you think in this case that the
osgi.compatibility.bootdelegation property would work? Unfortunately, this
isn't easily reproducible and just seems to happen at random.
We're running on eclipse 3.2.2. I saw that this property isn't documented
until eclipse 3.3. Was this ever back-ported?
Thanks,

osgi.compatibility.bootdelegation - if set to "true" then the parent (boot
by default) classloader is delegated to as a last resort if a class or
resource cannot be found. The default value is "true".
When launching Equinox under Eclipse the org.eclipse.equinox.launcher is
used to launch the framework (just like when you launch a normal Eclipse
SDK instance). Launching equinox this way enables the boot delegation
compatibility flag by default. Launching equinox with "-jar
org.eclipse.osgi ..." disables this option and Equinox will use strict OSGi
delegation rules for boot delegation.

Looks like starting Equinox under Eclipse makes the difference, although I
can't see what that would be (checked

suspicious)
Starting the same system bundle from the command line renders the expected
results:
> java -Dorg.osgi.framework.bootdelegation=org.w3c.* -jar
org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar -console -clean
osgi>ss
id State Bundle
0 ACTIVE org.eclipse.osgi_3.4.2.R34x_v20080826-1230
1 INSTALLED OSGiBootDelegationBundle_1.0.0
osgi> start 1
class java.lang.String
interface org.w3c.dom.Attr
If bootdelegation option is removed CNFE is thrown during start of the
bundle
Thx

Nice to find you here Rob
Yes I am certain (here are all the options that are set)
-Declipse.ignoreApp=true
-Dosgi.noShutdown=true
-Dosgi.clean=true
One thing I will admit that I am running Equinox within eclipse pde. I'll
try from the command line (not sure if it would make the difference)
see also: http://wiki.eclipse.org/Equinox_Boot_Delegation
(IIRC Equinox doesn't run in "strict" OSGi mode by default...)

Oleg,
Are you certain that the Equinox you are running in doesn't have the boot
delegation set to include org.w3c.*?

If I am reading the spec correctly only java.* are loaded from the
boot class path. All other packages must be declared
with explicit imports.
So something like this without
specifying org.osgi.framework.bootdelegation=org.w3c.*
public void start(BundleContext context) throws Exception {
System. out .println(Class.forName( "java.lang.String" ));
System. out .println(Class.forName( "org.w3c.dom.Attr" ));
}
should result in CNFE on the second line..
Well, it actually works just fine without bootdelegation option. I
figured I missed something, so may be some one can steer me in the
right direction.
Cheers
