JDK 8 Released

Most of us won’t be able to use/deploy JDK 8 in production for a looong time. But that shouldn’t stop us from using it, right?

It should be possible to sneak in JDK 8 in the back way, the same way we snuck in Groovy and other libraries we wanted to use.

The Maven compiler plugin run in two separate lifecycles, compile and testCompile. Those can be configured separately.

# Generate a unique private key (KEY)
sudo openssl genrsa -out mydomain.key 2048

# Generating a Certificate Signing Request (CSR)
sudo openssl req -new -key mydomain.key -out mydomain.csr

# Creating a Self-Signed Certificate (CRT)
openssl x509 -req -days 365 -in mydomain.csr -signkey mydomain.key -out mydomain.crt

# Append KEY and CRT to mydomain.pem
