RFR: 8240567: MethodTooLargeException thrown while creating a jlink image [v7]

[Oliver Kopp]

> Fix for [JDK-8240567](https://bugs.openjdk.org/browse/JDK-8240567): "MethodTooLargeException thrown while creating a jlink image".
> 
> Java still has a 64kb limit: A method may not be longer than 64kb. The idea of the fix is to split up the generated methods in several smaller methods
