proxy-property-sources=true causes ClassCastException

[greenarr0w]

Hello

I'm trying to use jasypt.encryptor.proxy-property-sources=true so that the PropertySources aren't wrapped, only proxied. We need this in our setup, because our internal framework has wrapped those PropertySources.

Versions:
jasypt-spring-boot-starter:3.0.5
org.springframework.boot:2.7.14

Now I'm getting the following ClassCastException. The exception happens with a plain spring boot app with the jasypt-spring-boot-starter (first I thought it has something to do with our setup, but it doesn't seem like it):

org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tomcatServletWebServerFactory' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/ServletWebServerFactoryConfiguration$EmbeddedTomcat.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'servletWebServerFactoryCustomizer' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/ServletWebServerFactoryAutoConfiguration.class]: Unsatisfied dependency expressed through method 'servletWebServerFactoryCustomizer' parameter 0; nested exception is org.springframework.boot.context.properties.ConfigurationPropertiesBindException: Error creating bean with name 'server-org.springframework.boot.autoconfigure.web.ServerProperties': Could not bind properties to 'ServerProperties' : prefix=server, ignoreInvalidFields=false, ignoreUnknownFields=true; nested exception is java.lang.ClassCastException: class org.springframework.core.env.PropertiesPropertySource cannot be cast to class com.ulisesbocchio.jasyptspringboot.EncryptablePropertySource (org.springframework.core.env.PropertiesPropertySource and com.ulisesbocchio.jasyptspringboot.EncryptablePropertySource are in unnamed module of loader 'app')

nested exception is java.lang.ClassCastException: class org.springframework.core.env.PropertiesPropertySource cannot be cast to class com.ulisesbocchio.jasyptspringboot.EncryptablePropertySource 

Is this a known issue or is there a way to fix it?

Thank you in advance.
