Paper: Test-First Java Concurrency for the Classroom
Test-First Java Concurrency for the Classroom 41st Technical Symposium on Computer Science Education (SIGCSE 2010) Concurrent programming is becoming more important due to the growing dominance of multi-core processors and the prevalence of graphical user interfaces (GUIs). To prepare students … Continue reading
SIGCSE Paper Accepted!
The paper that I submitted to SIGCSE a month and a half ago, “Test-First Java Concurrency for the Classroom”, got accepted! That means I’m going to Milwaukee in March. Update: I just realized that if my other paper currently under … Continue reading
New Version of DrJava with Mint
I just made a new release of the all-in-one DrJava with Mint: drjava-r5121-mint-r14186.jar On the Mint side, there is only one small change: Previously, the Mint compiler only appeared in the “Compiler” drop-down box if the “Display all compiler versions” … Continue reading
Today’s Loose Ends
I’m in the process of wrapping up today’syesterday’s loose ends: I made a new ConcJUnit release, 20091019, containing the files for versions 3.8.2 and 4.7, as described at the end of the last post. There is a new version of … Continue reading
Two Confusing Errors
A while ago, I was told by our one-and-only client of Mint that the version of DrJava with Mint does not display Mint as a compiler, even though it is included in the jar file and therefore should be available. … Continue reading
AWT Exception Handler Cannot Be Reset After Exception
When testing ConcJUnit some more from inside DrJava, I noticed some weird behavior. I had a JUnit 3.8.2 version of a test, and an equivalent JUnit 4 version. Run independently, they behaved as expected (which in my line of work … Continue reading
All in One File!
After integrating Mint into DrJava last week, we have now made it even simpler to experiment with Mint: You can download a copy of DrJava that already includes the Mint compiler, all in one file: DrJava with Mint (check the … Continue reading
DrJava with Mint Released
The latest releases of DrJava contains a compiler adapter for Mint. That means it is possible to conveniently compile Mint programs in the DrJava IDE. To experiment with Mint and DrJava, please do the following: Download DrJava with Mint the … Continue reading
DrJava Mint Branch Merged Back into Trunk
I just merged the trunk-mint branch of DrJava back into the trunk and made a new weekly release (@ I actually issue these “weakly” releases more often than just weekly. It’s just a convenient mechanism to benefit from the auto-update … Continue reading
OpenJDK Compatibility for ConcJUnit
I just made a new ConcJUnit release available on SourceForge: version 20090927. While working on integrating Mint into DrJava, I tested it on Mac. Since Mint requires Java 6, that involved using Soylatte, and Soylatte is based on OpenJDK. To … Continue reading
Running Mint Programs in DrJava
I have now managed to hack DrJava and Mint together. I still have to improve the source, because right now a few things are hard-coded, but it is a working proof-of-concept. Welcome to DrJava. Working directory is C:\Program Files\JavaMint\langtools\mintTest > … Continue reading
Installing JavaMint on Linux
Here are some quick instructions on how to download and install Java Mint. Linux You need Sun’s JDK 6 installed. Download the “binaries only” Java Mint zip file from the Java Mint implementation page. In this example, I have saved … Continue reading
Mint and DrJava Class Loader Issues
I’m still trying to integrate Mint into DrJava, and I’m running into a problem with the class loaders in Mint and DrJava. If I understand the class loader inside the Interaction JVM correctly (a PathClassLoader, I believe), it can change … Continue reading
DrJava with Mint Compiles on Windows, Mac and Linux
The DrJava built from my trunk-mint branch now manages to compile Mint programs on all three major operating systems: Windows, Mac and Linux. I had to make a bugfix in the Mint compiler (I will make a new release soon), … Continue reading
DrJava with Mint on Mac “Cosmetically” Closer
Sweet! DrJava with Mint on the Mac just came within reach, or at least as close as it is on the other operating systems. For some reason, when I ran DrJava under Soylatte and X11 earlier, no compilers showed up. … Continue reading
Mint in DrJava is Tricky
I’ve been trying to get the Mint compiler to work inside DrJava. This has turned out to be more tricky than I thought. The preempting class loader that we use to load different compiler adapters is still giving me headaches, … Continue reading
I Am (4*weakly+strongly)/5 Optimistic
The POPL 2010 reviews of our Mint paper are in. We got four reviews of “weak paper, but I will not fight against it” and one review of “strong paper, I will champion it at the program committee meeting”. We … Continue reading
