Spring Boot: Requests to / always redirected to Tasklist

Environment (Required on creation):

• Spring Boot starter 7.17.0+

Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket):

With the camunda.bpm.webapp.application-path property users can define the application path of the webapps. The default is /camunda/.
The camunda.bpm.webapp.index-redirect-enabled property lets users control if a request to / should be redirected to the Camunda webapps or not. When set to false the default Spring Boot behavior should apply. By default Spring Boot will serve a static index.html for those requests.

The issue occurs when camunda.bpm.webapp.application-path is set to / and camunda.bpm.webapp.index-redirect-enabled is set to false. The redirect to Tasklist is still performed, however the default Spring Boot behavior should take over instead.

Steps to reproduce (Required on creation):

1. Configure a 7.17.0 (or later) Camunda Spring Boot Starter:

• camunda.bpm.webapp.application-path=/
• camunda.bpm.webapp.index-redirect-enabled=false

2. Provide an index.html file under src/main/resources/static

2. Start the application and request send a GET request to localhost:8080/ (e.g. via browser)

Observed Behavior (Required on creation):

The request is redirected to Tasklist.

Expected behavior (Required on creation):

The request is not redirected to Tasklist. Instead, the static index.html is served.

Root Cause (Required on prioritization):

CAM-11911 introduced this filter which makes the redirect to Tasklist if the request URI matches the application path. In this case, the request URI is / which then should not be redirected.

Solution Ideas (Optional):

Only make the redirect if the requested URI is not /.
