> Similar to what was done in MCOMPILER-335 the default should now be 1.7, as that is the oldest version being supported by javac in Java 12 and Java 13 ([https://docs.oracle.com/en/java/javase/12/tools/javac.html#GUID-AEEC9F07-CB49-4E96-8BC7-BCC2C7F725C9__GUID-D343F6B4-3FDD-43A8-AD24-43DD70214471]).
> Otherwise compiling sources with Maven on Java 12+ will lead to errors in case no explicit source/target/release is set.
>  
> Note: ensure to update [[index.apt.vm|https://github.com/apache/maven-compiler-plugin/blob/maven-compiler-plugin-3.8.1/src/site/apt/index.apt.vm]|[https://github.com/apache/maven-compiler-plugin/blob/maven-compiler-plugin-3.8.1/src/site/apt/index.apt.vm]] as well.
