Specifically:</p> <p>The currentSchemaContext variable in this class is not thread safe. The "tryToUpdateSchemaContext" method is synchronized, but other places where we read the variable are not synchronized. This leads to "visibility" issues where an update to the variable may not be immediately visible in other threads.</p> <p>To fix this, we need to either make the variable currentSchemaContext volatile, or ensure that all access to it is synchronized. This can lead to indeterminate behavior.</p> <p>Operating System: All<br/> Platform: All</p> YANGTOOLS-189

Java Synchronization issues in URLSchemaContextResolver

Bug Resolved Done Tomas Olvecky Devin Avery Mon, 16 Jun 2014 13:04:41 +0000 Sun, 10 Apr 2022 18:35:08 +0000 Wed, 2 Jul 2014 09:06:42 +0000 Fri, 20 Jun 2014 00:00:00 +0000 0 5 <p>Agreed on non-safety. While a volatile may be a quickfix, the entire class is in need of complete redesign, making it very similar to the recent NotificationBroker rework: currentSourceContext and currentSchemaContext need to change atomically, which implies another level of encapsulation.</p> <p>While estimating the redesign, about 4-6 weeks back, I came to the conclusion that the APIs involved are not properly documented to make proper job of it, though.</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/8114/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/8114/</a></p> Development External issue ID 1198 External issue URL Rank 0|i025ov:
