Are you on Windows? Are you using the Tomcat service (procrun)? If so, then you have a Java tab somewhere.

Variable name:  Sun.io.useCanonCaches
Variable value:  false

Is this a Windows environment variable? If so, it will have no effect. It is also spelled incorrectly (cASe matTERs). If you end up setting a system preference, please spell it properly if you want it to take effect.

I'm curious, are you actually running Tomcat with read-only set to FALSE? You would only do that under very very VERY specific circumstances. And you would only allow authenticated access to your server, and already trust those users not to attack you, right?

Subject: Re: Setting sun.io.useCanonCaches to flase

add the following to setenv.bat

set CATALINA_OPTS=%CATALINA_OPTS% -Dsun.io.useCanonCaches=false

If running as a service then system properties are set on the Java tab.
You'd add:

-Dsun.io.useCanonCaches=false

Note: You only need to worry about this or CVE-2034-50379 if you have set 
readonly="false" on the default servlet.
