This major release announce the move from Cglib to ByteBuddy.
Sadly good old Cglib can’t cope with all the tricks needed to workaround JPMS and reflection limitations.
It means you will most probably experience some issues until it stabilizes.
The good news are that this version is working up to Java 18.
Known issues:
- Serialization of a mock is broken (#312)
- Running in OSGi doesn’t work (#313)
All help is greatly appreciated.
Change log
- Replace Cglib with Bytebuddy to support Java 9+ (#300)
- Fix core source-jar, added maven-source-plugin (#283)
- Upgrade to ASM 9.2 so that easymock can work with JDK18-EA #277 (#278)
- Upgrade to ASM 9.2 so that easymock can work with JDK18-EA (#277)
- Does not work with Java 17 (#274)
- Allow @Mock to get a default name from the variable being mocked (#260)
- Easymock doesn’t work in Java 11 with –illegal-access=deny (#235)

Support of Java 18 confirmed.

org.objenesis:objenesis-test missing in Maven Central (#85)- added instructions for running Android TCK for Windows users (#84)
- Copyright and Owner is missing in license (#83)

I’m not the best at diagnosing network issues.
Yes, in 99% of the cases, you think the problem is the network and it’s not.
But in rare cases it actually is.
A friend of mine has written an awesome guide to diagnose network issues using traceroute.
He also happens to have founded a startup named Okio doing network monitoring.
Read it, I have learned tons of things from it.
Full disclosure: In case of doubt, I have no interest in this company.
I do think they have a great product and that the guide is a fabulous piece of work.

We were talking about O’Reilly learning and books this morning.
For those who don’t know, I’m giving a Java course on O’Reilly every 2 months.
I thought it will be useful to create my list of books I think everyone should read.
I will keep it up to date so bookmark this page.
You can also find it on O’Reilly for the books available there (most of them).
In random order.

The list is quite incomplete.
I will add tons of books that worth your attention, but that’s a good start.
If you think watching videos and reading blog posts is enough, sorry you are wrong.
You will learn more with any of these books than by reading months of blog posts.

Update (2021-04-19): It’s a JDK bug. It was fixed in Java 11.
You can’t change user.dir anymore (see this).
But the behavior is consistent, user.dir is cached at the beginning.
I was playing with system properties lately.
My goal was to change the current directory.
The theory would be that the following code should do it.
System.setProperty("user.dir", Paths.get("build").toAbsolutePath().toString());
Surprisingly, it only half works.
If you use the good old File API, everything works well.
But it you use the new Path API, it does.
Here is the demonstration.
// Initialize out two file/path
Path path = Paths.get("target");
File file = new File("target");
// Print the absolute path for them, all good so far
System.out.println("file = " + file.getAbsolutePath());
System.out.println("path = " + path.toAbsolutePath());
// Change the current directory to a sub-folder
System.setProperty("user.dir", Paths.get("build").toAbsolutePath().toString());
// Print the absolute path again
System.out.println("file = " + file.getAbsolutePath()); // current dir changed
System.out.println("path = " + path.toAbsolutePath()); // uh-oh!
When using Path, the current directory doesn’t move.
Even if you create your Path after setting user.dir is doesn’t move.
It’s frightening because it’s not consistent.
Why do we have this behavior?
Because the java.nio.file.spi.FileSystemProvider implementation, UnixFileSystemProvider in my case, loads and cache
the current directory. The same happens on Windows. It’s not a Unix thing.
I must confess that I do not like the lack of consistency.
And I’m not sure I like not being able to fool around and change my system properties like I used to.

Let’s talk architecture today.
ArchUnit is a test framework to test an application architecture.
It is an interesting concept that I wanted to try out for a while.
So I did a little experiment on a Swing application I had.
It looks like unit tests with a fluent interface.
It’s quite nice to use.
I used Junit 5.
My two rules were simple:
- Backend should not use Frontend classes
- Backend should not use Swing or AWT classes
Using ArchUnit, it looks like this (in Kotlin):
@AnalyzeClasses(packages = ["pro.tremblay.myapp.."])
internal class BackendSegregationTest {
@ArchTest
val backend_doesnt_use_frontend = layeredArchitecture()
.layer("backend").definedBy("pro.tremblay.myapp.backend..")
.layer("frontend").definedBy("pro.tremblay.myapp.frontend..")
.layer("app").definedBy("pro.tremblay.myapp")
.whereLayer("frontend").mayOnlyBeAccessedByLayers("app")
@ArchTest
val no_ui_framework_on_backend = noClasses().that().resideInAPackage("pro.tremblay.myapp.backend..")
.should().accessClassesThat().resideInAnyPackage("javax.swing..", "java.awt..");
}
Two simple rules.
- One is defining my layers and how they should interact.
- The other is telling which packages are forbidden.
Sure enough, the test was failing.
I did some refactoring to repair everything and ta-da, for ever after, architecture will be enforced.
You might want to try it out on your own project.
I do recommend it.
