Deprecated Jakarta Servlet methods and classes have been removed in Jakarta Servlet 6.0. Remove the usage of these classes and methods from your application.

Removed Jakarta Servlet Classes:

`jakarta.servlet.http.HttpSessionContext`	None. The `jakarta.servlet.http.HttpSessionContext` class was removed for security reasons with no replacement.
`jakarta.servlet.http.HttpUtils`	This class was deprecated. Methods on the request interfaces provide similar functionality. `HttpServletRequest.getRequestURL()` can replace the functionality of `HttpUtils.getRequestURL(HttpServletRequest)` and `HttpServletRequest.getParameterMap()` can replace the functionality of `HttpUtils.parsePostData(int, ServletInputStream)` or `HttpUtils.parseQueryString(String)`.
`jakarta.servlet.SingleThreadModel`	None

`jakarta.servlet.http.HttpServletResponse.encodeUrl(String)` and `jakarta.servlet.http.HttpServletResponseWrapper.encodeUrl(String)`	`HttpServletResponse.encodeURL(String)` and `HttpServletResponseWrapper.encodeURL(String)`

This rule has an automated fix to replace the deprecated Jakarta Servlet classes and methods with their corresponding replacement. Copy the custom configuration to your application build file to enable the fix automation.
