test: Java 25 flexible constructor body

[seintur]

This PR provides a test to check the support of Java 25 flexible constructor bodies https://openjdk.org/jeps/513

thanks a lot @seintur the test passes so there is support out of the box?

[SirYwell]

Would it make sense to also have some printing tests?

[seintur]

Thanks @SirYwell for the recommendation. I have added some printing tests in 3ccc6f4

Hi @monperrus

Indeed JDT with compliance level 25 builds a correct AST, and the construction of the model by Spoon does not require any change.

In particular

spoon/src/main/java/spoon/support/reflect/code/CtBlockImpl.java

Line 169 in 3b73067

public <T extends CtStatementList> T addStatement(CtStatement statement) {

is used and does not enforce any other contract than adding the statement at the end of the list. So the ordering of statements as constructed by JDT in the AST is preserved by Spoon.

thanks a lot @seintur, @SirYwell and @I-Al-Istannen
