I decided to merge the drjava-guiAvailListener branch into the trunk, even though I said I wouldn’t do this until after the next stable release. Dr. Nguyen and I have used this new version quite a bit already, and we still … Continue reading →

I’m running the command line Javadoc tool. In the current directory, I have two files, A.java (which is syntactically correct), and a Broken.java (which has a syntax error in it). A.java doesn’t refer to Broken.java. File A.java: [cc lang=”java”]import javax.swing.JApplet; … Continue reading →

This morning, we got a support request for DrJava that mentioned path problems with the Media Computation library from Georgia Tech. While some of the problems mentioned could not be reproduced or were simply due to not understanding Java syntax, … Continue reading →

I finally implemented something this weekend that had annoyed me for a long time, ever since in July 2008 I introduced the feature to detach DrJava’s Tabbed Panes and the Debugger and put them into separate windows. These detached frames … Continue reading →

We’re working on three branches of DrJava and on the trunk right now. I don’t think we’ve seen this much parallel development in a while. In the trunk, for the last three days I’ve been working on a strange bug … Continue reading →

I just realized that I can just specify the top-level domain for the “site:” option in Google search queries. That allows me to search for DrJava on all .edu domains: drjava site:.edu I have already found a few more user … Continue reading →

At today’s JavaPLT/Habanero group meeting, Vivek mentioned that DrJava was used at UT-San Antonio as well. I added it to DrJava’s user sites.

Dung Nguyen and I just noticed that double-clicking on the application (or on the jar file) doesn’t bring up a new instance on his Mac (OS X 10.6). It does so on mine (OS X 10.4). In the end, we … Continue reading →

I’ve been trying to fix a memory leak in DrJava today. I found the reproducible memory leak quite quickly: When I added the right margin line feature, I added option listeners that change the color and position of the right … Continue reading →

Yesterday, Steve Gilbert notified me of a problem with the “smart run” feature I had introduced to simplify running applets and ACM Java Task Force programs. The problem was that I knew whether a class was an applet, an ACM … Continue reading →

Check out the right margin line that I just implemented. You can enable/disable it and change its position under Preferences/Display Options, and configure the color under Preferences/Display Options/Colors. By default, I have it enabled as light-gray line at 120 columns … Continue reading →
