Zakleszczenie odświeżania metadanych (wiosna-bezpieczeństwo-saml)

Question

co kilka dni nasza aplikacja internetowa korzystająca ze Spring Security SAML ma zakleszczenie. Zakleszczenie dzieje się podczas odświeżania metadanych.

Próbowałem również zrozumieć, co jest problem z kodu źródłowego, ale bez powodzenia.

to StackTrace trzech wątków, które znajdują się w martwym punkcie:

1. śledzenia stosu metadanych przeładowania [136] (zablokowany)

org.opensaml.saml2.metadata.provider.AbstractMetadataProvider.initialize line: 402 
    org.springframework.security.saml.metadata.ExtendedMetadataDelegate.initialize line: 167

    java.util.TimerThread.mainLoop line: 555 
    java.util.TimerThread.run line: 505 

2. ślad stosu czasowy-5 [135] (oczekiwanie)

Używamy:

1. wiosna-security-saml2-core 1.0.0.RELEASE
2. org.opensaml .opensaml 2.6.1

to metadane odświeżania config:

... 
     <!-- IDP Metadata configuration - paths to metadata of IDPs in circle of 
       trust is here --> 
     <bean id="metadata" 
       class="org.springframework.security.saml.metadata.CachingMetadataManager"> 
       <constructor-arg> 
         <list> 
           <bean class="org.opensaml.saml2.metadata.provider.HTTPMetadataProvider"> 
             <constructor-arg> 
               <value>https://www.example.org/saml2/idp/metadata.php</value> 
             </constructor-arg> 
             <constructor-arg> 
               <value type="int">5000</value> 
             </constructor-arg> 
             <property name="parserPool" ref="parserPool" /> 
           </bean> 
         </list> 
       </constructor-arg> 
     </bean> 
... 

Jak możemy rozwiązać ten problem?

Dzięki z góry, Denis

Answer 1

Jest to ważna kwestia, otworzyłem ticket w Jira i pchnął fix to master. Nowa wersja powinna być dostępna jutro pod numerem snapshot repo. Czy możesz ją przetestować ponownie?
