Bug ID: 65577
Summary: Intermittent AccessControlException using NIO2 with
security manager enabled
Product: Tomcat 8
Version: 8.5.70
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Connectors
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ----
We are doing some testing prior to upgrading from 8.5.66 to 8.5.70. When we
configure a SSL/TLS connector using Nio2 and run Tomcat with Security Manger
enabled we are getting intermittent java.security.AccessControlException errors
when accessing the default Tomcat root, e.g. https://hostname:8443/
We have observed the issue using Oracle Java 1.8.0_251, 1.8.0_301 and 11.0.8
2020-07-14 LTS on Windows Server 2019 and RedHat Linux 7.
When we change the connector configuration to use
org.apache.coyote.http11.Http11NioProtocol the errors are not present.
Example connector configuration
----------------
<Connector port="8443"
protocol="org.apache.coyote.http11.Http11Nio2Protocol"
maxThreads="150" SSLEnabled="true">
<SSLHostConfig>
<Certificate
certificateKeystoreFile="I:\tomcat-win\8.5.70\apache-tomcat-8.5.70\cert\tomcat.jks"
certificateKeystorePassword="xxxxx"
type="RSA" />
</SSLHostConfig>
</Connector>
The catalina.policy is the default one which comes with the 8.5.70 release
Startup command:
.\catalina.bat start -security
