What steps will reproduce the problem? 1. Upgrade from Tomcat 7.0.47 / Java 1.7.0_45 to Tomcat 7.0.50 / Java 1.7.0_51 What is the expected result? no errors logged. What happens instead? Errors (below) logged in catalina.out . These don't seem to be fatal to psi-probe functioning. What version of Probe are you using? 2.3.3 What environment (browser version, Tomcat version, JVM version, server OS)? RHEL 6, Java 1.7.0_51, Tomcat 1.7.50

After some digging, I've discovered this seems to be caused by tldValidation, by default this is set to false. But due to our setting org.apache.catalina.STRICT_SERVLET_COMPLIANCE=true tldValidation gets set to true.

Explicitly setting tldValidation=false in the context.xml results in this no longer being logged.

I'm not sure why this has only become an issue in since Tomcat 7.0.50, as we never encountered this with Tomcat 7.0.47 or earlier.

Is this a simple syntax issue in a TLD file that needs to be fixed?

Your pom.xml contains the following:

javax.servlet
jstl
1.1.0


taglibs
standard
1.1.0

Please update those both to
1.1.2.

The TLD files in Apache Jakarta Standard Taglib 1.1.0 (standard-1.1.0.jar) are broken as they have wrong value for xsi:schemaLocation attribute.
