Spring Property placeholder with colon now considered as default value since 6.2

Prior to Spring 6.2 I used to have a property like: my.prop: ${safestore:///my/path}

With a custom property source:

public Object getProperty(String name) {
        if(name.startsWith("safestore:/")) {
              return ...
        } else {
             return null;
       }
}

With Spring 6.2, 'name' doesn't contain the full placeholder 'safestore:///my/path' anymore but only 'safestore'. I guess this is now considered as a default value as it resolves to '///my/path'.

Is this expected behavior with Spring 6.2? If so, how could I achieve the same behavior as before?

Note: my property source is recorded with

environment.getPropertySources().addAfter(
                StandardEnvironment.SYSTEM_ENVIRONMENT_PROPERTY_SOURCE_NAME,
                new KhanPropertySource(PROPERTY_SOURCE_NAME));

the full placeholder 'safestore:///my/path' anymore

This isn't a placeholder. The placeholder is safestore with a fallback value of ///my/path if no safestore property exists in the environment.

See #34124

: is a reserved keyword. The fact that you had to use your own property source to make this work is a sign that it isn't right. We've restored support purely because it used to be supported before but you should find a format that doesn't use the reserved keyword. Or you can escape it with \.

Ha sorry I missed the duplicate.

We will wait for 6.2.2 then and adapt our code to avoid usage of ':' in the future.

Thanks @snicoll for your quick reply,
