Re: STRUTS_EXAMPLES_1_1_0

|It seems to me that you’ve compiled struts example war with one jdk and are running tomcat with a different one?
|I did everything with the same jdk version, to be precise it is

  The parent has:

<maven.compiler.source>17</maven.compiler.source>
<maven.compiler.target>17</maven.compiler.target>
<struts2.version>6.3.0.2</struts2.version>

If I change this to 1.8, and test, (on  8,11,17) I do get the leak when 
undeploying a few times :

The following web applications were stopped (reloaded, undeployed), but their
classes from previous runs are still loaded in memory, thus causing a memory
leak (use a profiler to confirm):
/helloworld
/helloworld
/helloworld
