Hudson = 1.262
Access Control = Active Directory
Authorization = Matrix based Security

I restart Hudson by doing the following:
net stop "Apache Tomcat"
net start "Apache Tomcat"

After a restart, any attempt to access Hudson produces the following error:

org.springframework.beans.factory.BeanCreationException: Error creating bean

org.springframework.beans.BeanInstantiationException: Could not instantiate bean

The only workaround I've found is to:

1. edit config.xml and either set "<useSecurity>false</useSecurity>" or remove
the following element:

2. Restart Hudson again. It works now, but naturally the security system is
missing.

3. Restore the original config.xml.

4. Restart Hudson a second time. Hudson now works correctly, until the next
restart.

This doesn't make sense. When you stop Tomcat, its JVM exits. So there's nothing
that "remembers" what the previous execution about.

Whereas you report that the behavior differs with the same config.xml, depending
on what its previous execution was like.

Do you have other plugins installed? Perhaps there's some interference along
that line?

This exception happens for me too now.
I am running hudson on a tomcat 6 server and I restarted Hudson and the
exception occurred. I furhter tried to restart tomcat but that didn't change
anything too.

A thing that I did (tried to remove the changes again but the exception still
occurs) is that I changed the server.xml from tomcat by adding UTF8 stuff:

from:
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"/>
to
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
URIEncoding="UTF-8" />

but I don't think that this had any influence...

I have several other Plugins installed on my system (Perforce, Nant, MSBuild,
Nunit, Disk Space, Additional Sidebar, Active Directory,...)

I commented the following info in the config.xml and hudson starts up correctly
again:
<authorizationStrategy class="hudson.security.AuthorizationStrategy$Unsecured"/>
<securityRealm
class="hudson.plugins.active_directory.ActiveDirectorySecurityRealm"/>

but when trying to enable active directory again I get a 500 error in the UI

javax.servlet.ServletException:
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'activeDirectory': Instantiation of bean failed; nested exception is
org.springframework.beans.BeanInstantiationException: Could not instantiate bean

User\.hudson\plugins\active-directory\WEB-INF\lib\com4j.dll already loaded in
another classloader

and further on - as it is already posted in this defect

I'm using 1.309
