Spring 6.2.10 getResource(String location): returns null #35467
Description
Environment:
- Spring Framework: 6.2.10
- Java: 17
package org.springframework.core.io;
/**
* Return a {@code Resource} handle for the specified resource location.
* <p>The handle should always be a reusable resource descriptor,
* allowing for multiple {@link Resource#getInputStream()} calls.
* <p><ul>
* <li>Must support fully qualified URLs, for example, "file:C:/test.dat".
* <li>Must support classpath pseudo-URLs, for example, "classpath:test.dat".
* <li>Should support relative file paths, for example, "WEB-INF/test.dat".
* (This will be implementation-specific, typically provided by an
* ApplicationContext implementation.)
* </ul>
* <p>Note that a {@code Resource} handle does not imply an existing resource;
* you need to invoke {@link Resource#exists} to check for existence.
* @param location the resource location
* @return a corresponding {@code Resource} handle (never {@code null})
* @see #CLASSPATH_URL_PREFIX
* @see Resource#exists()
* @see Resource#getInputStream()

}Even though getResource could not return null, the exception occur.
java.lang.NullPointerException: Cannot invoke "org.springframework.core.io.Resource.exists()" because "resource" is null
