-----------------------------------
Summary: Freemarker 2.3.33 causes bytecode version compatibility
issues when transitively provided by Struts 6
Key: WW-5581
URL: https://issues.apache.org/jira/browse/WW-5581
Project: Struts 2
Issue Type: Bug
Affects Versions: 6.8.0, 6.7.4, 6.7.0, 6.6.1, 6.6.0
Reporter: Frédéric Hannes
Freemarker 2.3.33 introduced an issue with Java 8 because it introduced a files
for newer versions of Java. This seems to introduce issues in some application
servers, as well as with the Maven Enforcer Plugin when it checks for bytecode
compatibility with Java 8. This issue was resolved in version 2.3.34 of
Freemarker ([https://freemarker.apache.org/docs/versions_2_3_34.html)] with
PR110: [https://github.com/apache/freemarker/pull/110]
Struts 6 still has not updated to the latest version of Freemarker to resolve
this issue, unlike version 7. But Struts 6 still targets older versions of the
JEE spec with Java EE, that still support Java 8, so this can cause
compatibility issues if the project using Struts does not explicitly replace
the Freemarker dependency with the latest version.
