Sybex CSG 11: Some mistakes

[Roy van Rijn]

We noticed some mistakes in the Sybex CSG 11 book.

Some of them were already mentioned here, I checked :-)

I lost most of my notes, but here are some I didn't see on the site:

page 835: Question 9:
The flag "--internal-jdk" doesn't exist, it should be "--jdk-internals".

page 907: Question 20:
service.execute() is being called instead of .submit().
But there is a bigger issue: service isn't effectively final and can't be used in the lambda.

page 962/963: Question 10, answer F:
All instance members of the class must be serializable or marked "transient".
Page 941 mentioned that having 'null' at time of serialization is also an option, which isn't mentioned.

Thanks!  I've confirmed the errata and updated the book pages:

Appreciate you finding these so we can make sure they don't make it into our upcoming Java 17 book!

Note that the first one was in the errata as page 1160. (The answer is H for the question as written)
