reverse merge of workspace settings not sorting properties anymore

[hohwille]

1. devon eclipse ws-reverse
2. check your *.prefs files

Expected result:
*.prefs files should be sorted alphabetically to make diffs of git changes more readable

Actual result:
*.prefs files seem to be in the order as written by eclipse (=chaotic order).

Seems something broke here:

ide/configurator/src/main/java/com/devonfw/tools/ide/configurator/SortedProperties.java

Line 18 in 2846c26

public class SortedProperties extends Properties {

Maybe happened due to newer Java version and changed behaviour of java.util.Properties.

Please add a JUnit Test creating SortedProperties, writing to String and then assert the result is in alphabetical order. This test should fail. Then fix the issue and verify the test got green.

As no-one took over, I will do this...

Problem was that keySet was overriden to apply sort but with more recent Java (after 1.8) version entrySet is used by store method instead of keySet.
As you can see in PR #490 we need to also override entrySet and sort the resulting set to fix and make it work also with newer JDK (11+).
