Still trying to deploy and get my server running .. As my Cloud SQL database is getting initialized I am getting the following exception:
[main] ERROR com.mz.server.BootstrappingServerConfig - Error trying to migrate SQL scripts ..

I am not sure what information I should deliver here - this would be my app.yaml:
runtime: java
vm: true
runtime_config:
jdk: openjdk8
server: jetty9
env_variables:
'ALPN_ENABLE': 'true' # OPTIONAL
beta_settings:
cloud_sql_instances: mahlzeit-test:us-central1:mahlzeit-life-cloudsql-prod
health_check:
enable_health_check: false
This is how I am configuring my DataSource in my Spring Application Context:
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://google/mz_db?cloudSqlInstance=mz-test:us-central1:mz-life-cloudsql-prod&socketFactory=com.google.cloud.sql.mysql.SocketFactory" />
<property name="username" value="root" />
<property name="password" value="" />
</bean>
The compute instances which are accessing the Cloud SQL instances are in the same project.
Why am I getting
java.lang.IllegalAccessError: tried to access field sun.security.ssl.Handshaker.localSupportedSignAlgs from class sun.security.ssl.ClientHandshaker
and how can I fix this?

The problem was
env_variables:
'ALPN_ENABLE': 'true' # OPTIONAL
which I simply used from a tutorial without thinking about what that is/means.
ALPN is a library which appears to optimize HTTPS requests. I tried to add the library to my dependencies which did not work. Maybe I got the wrong version or something like that. However, at the moment this is no requirement for me.
To solve the issue I simply removed this variable. Setting it to 'false' should also do it.
