--------------------------------
Summary: Execute and Wait Interceptor prevents JVM shutdown
Key: WW-5289
URL: https://issues.apache.org/jira/browse/WW-5289
Project: Struts 2
Issue Type: Bug
Components: Core Interceptors
Affects Versions: 6.1.1
Reporter: KON-SUN-TACK
Hi Struts 2 team,
We are using the Execute and Wait Interceptor as following:
{{ <action name="longRunLaunch"
class="my.sample.longrun.action.LongRunAction"
method="longRunLaunch">
<interceptor-ref name="myStack"/>
<interceptor-ref name="execAndWait">
<param name="delay">500</param>
<param name="delaySleepInterval">500</param>
</interceptor-ref>
<result name="wait">/my/sample/wait.jsp</result>
<result name="success">/my/sample/success.jsp</result>
</action>}}
- with Struts 6.0.3, it works fine
- with Struts 6.1.1, it works fine... but JVM shutdown is hanging
We are running: Apache Tomcat (TomEE)/9.0.41 (8.0.6)
I tried to compare thread dumps and only found this extra one with Struts 6.1.1:
