Kim Shepherd commented on DS-785:
---------------------------------
Update: I can reproduce Keiji's exact error by ensuring that 'discovery' is
*replacing* search in the list of event consumers rather than just adding it to
the list.
So replacing search with discovery will ensure that KernelManager is loaded,
but then fails at slf4j init when trying to access the SINGLETON field.
According to the slf4j FAQ, the SINGLETON field is private (and accessing it
throws this IllegalAccessError) in versions 1.5.6+.
Link to full discussion of error on the slf4j FAQ:
http://www.slf4j.org/faq.html#IllegalAccessError
dspace-solr module does indeed include version 1.5.6 of slf4j:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.5.6</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-jdk14</artifactId>
<version>1.5.6</version>
</dependency>
We either need to roll back to slf4j or update code to handle the change in
access to org.slf4j.impl.StaticLoggerBinder
