Setting OSGi config for LinkInfoStorageImpl via source package does not work

Hi folks

I am currently trying to set the OSGi configuration for com.day.cq.rewriter.linkchecker.impl.LinkInfoStorageImpl via a source content package (/apps/.../config/...) in AEM6. My XML looks like this:

<?xml version="1.0" encoding="UTF-8"?> <jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" jcr:primaryType="sling:OsgiConfig" service.max_links_per_host="{Long}500" service.save_external_link_references="{Boolean}false" />

As soon as I deploy such a content package with the above content the publish instance does not work anymore and I can see a lot of error messages like the following:

11.06.2015 14:21:52.170 *ERROR* [pool-5-thread-5] com.day.cq.cq-rewriter [com.day.cq.rewriter.linkchecker.impl.LinkInfoStorageImpl(1170)] The activate method has thrown an exception (java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer) java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer

Next I checked /crx-quickstart/launchpad/config/com/day/cq/rewriter/linkchecker/impl/LinkInfoStorageImpl.config and observed the following:

When setting the max links setting via web console the following gets written to the file.

service.save_external_link_references=B"false" service.pid="com.day.cq.rewriter.linkchecker.impl.LinkInfoStorageImpl" service.max_links_per_host=I"500"

When setting the max links value via a source package with the above XML snippet the following gets written to the file.

service.pid="com.day.cq.rewriter.linkchecker.impl.LinkInfoStorageImpl" service.save_external_link_references=B"false" service.max_links_per_host=L"500"

So apparently the configuration of the max links setting must be an integer value. However I don't know how to set an integer value via XML configuration. Am I missing something here? I thought that {Long} is the only possibility to define a number value. I also tried {Integer} just to be sure but that did not work either (in fact it prevents the config file from getting created). Did anybody else have this kind of problem and has a solution for it? I thought I ask here first before opening a daycare ticket. Any help is appreciated.

Cheers

Running into the same issue with Adobe Granite Workflow Service! (com.adobe.granite.workflow.core.WorkflowSessionFactory)

Either "cq.workflow.job.retry" or "granite.workflow.inboxQuerySize" require to be set as integers but any attempt to use {Long} would end up with the same error described above

java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer

In my case and on AEM 6.1 , it will actually completely break the touch UI by throwing a 500 response in the JS console...

Is there a way to make attributes of sling:OsgiConfig node via XML use Integer like {Long} or {Boolean} are used?

Thanks!

Just sharing my findings here.

This happens only if the @2542150 SRC annotation uses "intValue".

It may simply be not supported at the Sling level with the Jcr Installer not supporting all types (https://issues.apache.org/jira/browse/SLING-2477) ?

There are several options I could think of that I will explore:

1) left out the integer values from the xml config file and let the default be use for these. Luckily, I don't need to override the default for these attributes. @smacdonald2008, does that sound weird / not recommended?

<?xml version="1.0" encoding="UTF-8"?> <jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0" jcr:primaryType="sling:OsgiConfig" adapter.condition="If the ResourceResolver is a JcrResourceResolver or a Session." cq.workflow.models="/etc/workflow/models" cq.workflow.instances="/etc/workflow/instances" cq.workflow.workspace="crx.default" cq.workflow.superuser="[admin,administrators,some-user]"/>

instead of

<?xml version="1.0" encoding="UTF-8"?> <jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0" jcr:primaryType="sling:OsgiConfig" adapter.condition="If the ResourceResolver is a JcrResourceResolver or a Session." cq.workflow.models="/etc/workflow/models" cq.workflow.instances="/etc/workflow/instances" cq.workflow.workspace="crx.default"cq.workflow.job.retry="3"cq.workflow.superuser="[admin,administrators,some-user]"granite.workflow.inboxQuerySize="2000"/>

2) Try to serve a nt:file based osgi config that could be picked up by the JCR Installer and be "type friendly" like this:

# Configuration created by Apache Sling JCR Installer cq.workflow.superuser=["admin","administrators","other-user"] cq.workflow.workspace="crx.default" adapter.condition="If\ the\ ResourceResolver\ is\ a\ JcrResourceResolver\ or\ a\ Session." cq.workflow.models="/etc/workflow/models" cq.workflow.instances="/etc/workflow/instances" cq.workflow.job.retry=I"3" granite.workflow.inboxQuerySize=I"2000"

Not sure if that is even possible, just throwing things and see if they stick.

Basically, from an XML file defining a sling:OsgiConfig node (i.e /apps/thing/config/some.pid.config.xml), what would be the best practice to set values of "intValue" defined in SCR annotations?

@Property(intValue={42}, name="answer", label="Answer to life")

-->

<?xml version="1.0" encoding="UTF-8"?> <jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0" jcr:primaryType="sling:OsgiConfig" answer="42"/>

Thanks!

"I thought that {Long} is the only possibility to define a number value."

What give you that impression - did you read an online doc that stated this?
