Don't use LruCache

[nk-coding]

Is your feature request related to a problem? Please describe.
We have a dependency which

• uses the Java 9 module system
• has dependencies to junit framework and engine

LruCache is in the module org.junit.platform.commons.util, which is not exported, which then causes issues (the class def is not found)

Describe the solution you'd like
Not use the LruCache (maybe an own implementation instead? It basically just overwrites LinkedHashMap.removeEldestEntry)

Describe alternatives you've considered

AJTS-Version you are using
1.3.2

Yes, I can change that, of course. I thought it would be a good idea to avoid having yet another LRU implementation, but this is a problem, of course (it would also be one for #10). I will do that today.

This should now be fixed in version 1.3.4 with commit defb7ae.
