Spring Large unnecessary memory allocation rate in Spring Boot 2.6.2 Web MVC

I noticed in Opsian Profiler, that somehow the org.springframework.web.util.ServletRequestPathUtils#getParsedRequestPath method in our services allocates memory everytime it is called. And it is called a lot. For high RPM simple services, the memory allocation from it can be as significant as 30% total of all memory allocations.

The source code of ServletRequestPathUtils#getParsedRequestPath is:

    public static RequestPath getParsedRequestPath(ServletRequest request) {
        RequestPath path = (RequestPath) request.getAttribute(PATH_ATTRIBUTE);
        Assert.notNull(path, "Expected parsed RequestPath in request attribute \"" + PATH_ATTRIBUTE + "\".");
        return path;
    }

I would assume, the author expected the Expected parsed RequestPath in request attribute \"" + PATH_ATTRIBUTE + "\". to be compiled into a constant, however JD-GUI decompiler shows it still as: Assert.notNull(path, "Expected parsed RequestPath in request attribute \"" + PATH_ATTRIBUTE + "\".");

The problem arises, because public static final String PATH_ATTRIBUTE = ServletRequestPathUtils.class.getName() + ".PATH"; is not a compile time constant, but a runtime constant.

So at least one, new, relatively long, and unnecessary, String is allocated every time this method is called.

One Profiler sample stacktrace (there are other stack branches):

I have seen lots of effort put under making Spring Boot more memory (allocation) efficient, in last 2 years, thank you for that. But it seems like there is an opportunity to make it even better.
