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

I have a Spring Boot application with following SSL configuration:


port: 443
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:



java -jar target\myapp-

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- -env=dev "-envvars.X_KEYSTORE_PASSWORD=correctpassword"

App fails to start with this stacktrace:

vb-c2b995f3 -> 2016-11-17 15:31:56.659 ERROR 636 --- [ main] o.apache.catalina.core.StandardService : Failed

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

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