JasperException: PWC6033: Error in Javac compilation for JSP

[DerReparator]

When trying to run the Lab6 Maven Project (OSLC4J Bugzilla adapter), I can successfully start the application. But as soon as I try to access the OSLC Catalog via this link, the application throws an error in the console and only displays an empty page.

In my pom.xml, I set 1.8 as the maven compiler target but that didn't change anything.

I followed the tutorial on this webpage: OSLC Reference

The error:

Nov. 09, 2021 3:26:56 PM org.apache.jasper.compiler.Compiler generateClass
SEVERE: Error compiling file: /Users/phil/lyo.docs/lyo-rest-workshop/Lab6/target/tmp/jsp/org/apache/jsp/cm/serviceprovidercatalog_005fhtml_jsp.java
