Spring Boot app does not start due to SSL error on Boxfuse Dev VM

I have a Spring Boot application with following SSL configuration:

application.yml

server:
port: 443
ssl:
key-store: classpath:keys/${BOXFUSE_ENV}.p12
key-store-type: PKCS12
key-alias: mydomain.com
key-store-password: ${X_KEYSTORE_PASSWORD}


The correct environment-specific keystores are present in classpath and accessible after launch, which has been verified by manual launch from console with following PowerShell script:

dev.ps1

$env:BOXFUSE_ENV="dev"
$env:X_KEYSTORE_PASSWORD="correctpassword"

java -jar target\myapp-1.0.0.12314.jar


After manual start application successfully launches at localhost and available both in production and dev mode with correct certificates.
Now, I try to launch it in PowerShell as Boxfuse app with following command:

boxfuse run target\myapp-1.0.0.12314.jar -env=dev "-envvars.X_KEYSTORE_PASSWORD=correctpassword"


App fails to start with this stacktrace:

What makes so big difference between the two ways to launch the app? How can I fix it?

Answer

The key length could point to JDK unlimited strength crypto which may need to be enabled. See https://boxfuse.com/docs/payloads/springboot#jce
