[jbosstools-issues] [JBoss JIRA] (JBIDE-9874) Weird NPE when publishing
[
https://issues.jboss.org/browse/JBIDE-9874?page=com.atlassian.jira.plugin...
]
Rob Stryker commented on JBIDE-9874:
------------------------------------
There is still only one behaviour model, so there is a singleton lookup of the entry
point. It is all loaded upon first load of the model via extension points. So even if two
different threads get in here at the same time, both threads will load the exact same
model, since it is entirely loaded via extension points. There would then be two models,
both containing the exact same thing, but only one would be stored in the variable. All
subsequent calls will use the version stored in the variable. The second model will be
garbage collected after the first use.
What should be done to make the "dangerous singleton" less dangerous?
