[SYNCOPE-1448] Ensure Java 8 compatibility (2nd take)
> Bean loading/register section not threadsafe
> --------------------------------------------
>
> Key: SYNCOPE-1448
> URL: https://issues.apache.org/jira/browse/SYNCOPE-1448
> Project: Syncope
> Issue Type: Bug
> Components: core
> Affects Versions: 2.1.3
> Reporter: longstone
> Assignee: Francesco Chicchiriccò
> Priority: Major
> Fix For: 2.1.4, 3.0.0
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Issue:
> When two threads (T1,T2) arrive the section {{if
> (ApplicationContextProvider.getBeanFactory().containsSingleton(ruleClass.getName()))
> {}}at the same time they will both assume that there is no bean, which is
> right so far.
> T1 register the bean as it should here
> {{ApplicationContextProvider.getBeanFactory().registerSingleton(ruleClass.getName(),
> rule);}}. As soon as T2does the same, an exception is thrown.
> Solution:
> When T1 and T2 found that a given bean is not there, they'll hit a
> synchronized section with double checking. This will prevent the duplicated
> creation and registration of a bean.
