Andreas Falk a085a12c99 Fix wrong java runtime version mentioned in reference doc
The reference documentation still referred to Java 5.0 as minimum
runtime version which is wrong.
This commit changes this to the correct
Java 8 runtime version as required minimum version.
In addition it corrects a fuzzy wording regarding stripping down the
`spring-security-core` jar.

Fixes gh-7440
