There are some problems when running WAS (Tomcat).

[kdaek21]

Thank you for creating a JVM that runs on .NET.

When I tried to run WAS (Web Application Server) on IKVM and set Tomcat to run on IKVM, it crashed with a StackOverflowException. So I tested it by removing the option parts created in the batch file used when running Tomcat one by one, and confirmed that it crashed with the exception when the '-Djava.protocol.handler.pkgs=org.apache.catalina.webresources' option was entered.
The comment for the option part is as follows.

rem Register custom URL handlers
rem Do this here so custom URL handles (specifically 'war:...') can be used in the security policy

It seems that a class inside the 'org.apache.catalina.webresources' package inside Tomcat is doing some work and causing a StackOverflowException. In the net472 version, it only displays the message 'Process is terminated due to StackOverflowException.' and dies, but in the net8.0 version, it shows a detailed call stack, so you can check where the exception occurs. The original Java made in C or C++ does not cause this exception. Is there a possibility that this issue will be resolved in a future version?

Also, when the WAS (Tomcat) starts and the first connection is made, it takes a long time to compile the JSP. Is there a possibility that this issue will be resolved?

Going to need more information, such as the stack trace, etc.

The net472 version only shows the message 'Process is terminated due to StackOverflowException.', so I attached the Stacktrace from running it on the net8.0 version.
