longstone created SYNCOPE-1448:
----------------------------------
Summary: 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
Reporter: longstone
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.
