Disconnected from the target VM, address: '127.0.0.1:53506', transport: 'socket'

Process finished with exit code 1`

Environment
spring AI version: 1.0.0
Java 21
Spring boot 3.3.4

Properties file I have set these properties

`spring.ai.vertex.ai.embedding.project-id=<YOUR_PROJECT_ID>
spring.ai.vertex.ai.embedding.location=<YOUR_PROJECT_LOCATION>
 
`

To temporarily make it work I tried to add these properties, but none work

spring.ai.model.embedding.text=none
spring.ai.vertex.ai.embedding.enabled=false //docs suggest this is deprecated.

Steps to reproduce
Add vertext embedding dependency and add properties in .properties file.

Expected behavior
Application should start and dependencies should not be corrupted.

Minimal Complete Reproducible example
Please provide a failing test or a minimal complete verifiable example that reproduces the issue.
Bug reports that are reproducible will take priority in resolution over reports that are not reproducible.

Start with VertexAiEmbeddingConnectionAutoConfiguration.connectionDetails and VertexAiEmbeddingConnectionDetails.Builder.build, following the stack trace through PredictionServiceSettings and InstantiatingGrpcChannelProvider. Reproduce the Spring AI 1.0.0 setup with Java 21, Spring Boot 3.3.4, and the listed Vertex AI properties, then verify that the application starts without the SecureSessionAgent ClassNotFoundException.
