[jdk8u-dev] RFR: 8265527: tools/javac/diags/CheckExamples.java fails after JDK-8078024 8u backport [v2]

[Peter Zhelezniakov]

> This fix reverts some of the changes made to jtreg tests by the 8078024 backport. Changes to javac itself are not reverted.
> 
> The failing test checks error messages emitted by javac while compiling invalid code. The exact messages differ in JDKs 8 and 9, where 8078024 fix was backported from. So this fix updates the expected messages to match those issued by JDK8.
