Hello again
Moving on to XWiki 5.1 did the trick, except that I run into another
trouble ...
When my job is starting, I get a NPE:
Exception in thread "Job Manager daemon thread"
java.lang.NullPointerException
at
org.xwiki.job.internal.AbstractJob.jobStarting(AbstractJob.java:170)
at org.xwiki.job.internal.AbstractJob.run(AbstractJob.java:134)
at
org.xwiki.job.internal.DefaultJobManager.runJob(DefaultJobManager.java:131)
at
org.xwiki.job.internal.DefaultJobManager.run(DefaultJobManager.java:110)
at java.lang.Thread.run(Unknown Source)
It's on following "this.logger..." line in AbstractJob:
if (getStatus().getRequest().getId() != null) {
this.logger.info("Starting job of type [{}] with
identifier [{}]", getType(), getStatus().getRequest()
.getId());
} else {
I checked and getType() is not null. The other can't be. So could it be
that this.logger is null ?
Could it be again a pb of root component manager ?
BR,
Jeremie
