Paper: Mint: Java Multi-stage Programming Using Weak Separability
Mint: Java Multi-stage Programming Using Weak Separability 2010 ACM SIGPLAN Conference on Programming Language Design and Implementation (PLDI 2010) Multi-stage programming (MSP) provides a disciplined approach to run-time code generation. In the purely functional setting, it has been shown how … Continue reading
Java Bug 4396719 Work-Around?
It seems like I can get around the garbage collector bug if I use -XX:+UseConcMarkSweepGC JVM argument. Now I’m having more Soot problems, but they actually make sense. In addition to being cross-platform, DrJava is also “cross-JDK version”: We support … Continue reading
Soot Build Instructions
While trying to create a call graph of DrJava using Soot, I ran into some problems that were supposed to have been fixed in the Soot nightly builds already. Unfortunately, the nightly builds I could find were all many months … Continue reading
A HotSpot Java Error, a Bus Error and a Segmentation Fault
When I run Soot to create a call graph of DrJava, I get the aforementioned HotSpot Java error on Windows with Java 1.6.0_18. On Mac OS X 10.4 with Java 1.5.0_19, I get a “Bus error” (Java exit status 138). … Continue reading
Mint Paper Accepted to PLDI 2010
I’m happy to report that our Mint paper “Mint: Java Multi-stage Programming Using Weak Separability” has been accepted to PLDI 2010 in Toronto! I couldn’t find the deadline for submitting the camera-ready version yet, and the reviewer and referee comments … Continue reading
Subversion “obliterate”
Apparently, Subversion is adding support for an “obliterate” command that can delete a file completely, including from the revision history. I once had to do this because I accidentally added a license file that needed to be kept private into … Continue reading
More Details on Soot and -allow-phantom-refs
In the previous post I mentioned that I’m trying to create a call graph of all of DrJava using Soot. Since DrJava is a cross-platform application, there are classes that get compiled and used only on certain operating systems. The … Continue reading
Java Bug 4396719 – Mark Sweep stack overflow on deeply nested Object arrays
I’m trying to create a call graph of all of DrJava using Soot. DrJava is a cross-platform application that has some classes that get compiled and used only on certain operating systems; for example, the com.apple.eawt package is only used … Continue reading
Sometimes I Love Myself
Sometimes I have those moments when something small that I did brings me tremendous joy. This just happened when I was using DrJava with Soot. I don’t know the Soot framework, so the “Additional Javadoc URLs” feature that I introduced … Continue reading
IT Hell
Building emacs22 to replace emacs21, so I can install yasnippet, so I can install scala-tool-support, because I can’t install Eclipse since it requires Mac OS 10.5 and I only have 10.4 because Apple doesn’t support Java 6 on 32-bit Macs… … Continue reading
Broken Things 2010
So far, it seems like 2010 is a year of broken things. Mr. Coffee, my coffee maker, broke. I loved the guy, so I immediately replaced him with his younger brother. The power supply fan in my Dell at home … Continue reading
Another Possible Improvement
On the other hand, I think I can re-enable checking if the event thread has finished and generating EventThreadStillProcessingErrors in the “update” Runnable that sets the test thread group the event thread uses, at least in certain cases. It is … Continue reading
Another Possible Problem
I think I have just realized that this still isn’t good enough. Now we know that there aren’t any more events, but it is conceivable that a Runnable executing just before the token Runnable has started new threads. Those threads … Continue reading
New Release of ConcJUnit: 20100112
I’ve just made a new release of ConcJUnit: 20100112. This release contains an important addition that I had been thinking about for a while. ConcJUnit already detected failures and uncaught exceptions in the event thread, but since the event thread … Continue reading
Auto-Upgrade to WordPress 2.9
I just performed an WordPress auto-upgrade to version 2.9. Version 2.9 requires MySQL version 4.1.2, and 1&1 was only running version 4.0.27. However, I found out that MySQL 5.0 is also running, so I needed to export the MySQL 4.0 … Continue reading
