Trying to use a plugin that uses spring-mvc might cause the following exception:
[INFO] [talledLocalContainer] java.lang.ClassCastException: org.springframework.web.context.request.async.WebAsyncManager cannot be cast to org.springframework.web.context.request.async.WebAsyncManager
[INFO] [talledLocalContainer] at org.springframework.web.context.request.async.WebAsyncUtils.getAsyncManager(WebAsyncUtils.java:46)
[INFO] [talledLocalContainer] at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:960)
[INFO] [talledLocalContainer] at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:857)
This is due to spring-mvc setting a request attribute with the WebAsyncManager in core (using Spring3), and spring request processing in the plugin trying to reuse it and cast it to the Spring4 version, which fails.
A workaround is to declare a servlet-filter module in the plugin that will handle cleaning the request attribute before further processing:
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
if (request.getAttribute(WebAsyncUtils.WEB_ASYNC_MANAGER_ATTRIBUTE) != null) {
request.setAttribute(WebAsyncUtils.WEB_ASYNC_MANAGER_ATTRIBUTE, null);
}
Hi,
At Atlassian, our goal is to ensure we’re providing the best experience for our customers. With our new Data Center strategy, Atlassian's focus is on security, compliance, and performance and is a key driver in prioritizing bugs. Closing the bugs that do not fall into those categories will allow us to focus on the ones in the most current versions of our products.
This bug is being closed due to a lack of engagement in the last four years, including no new watchers, votes, or comments; this inactivity suggests a low impact.
