Hasnae brings in a precious engineering experience from her years at Atlassian working on Confluence.
A Java architect by trade, after 16 years of Java, and in the spirit of keeping her tech life interesting , Hasnae decided to embrace yet another tech stack (Golang) explore a new product and learn both from the best in Sydney aka. SafetyCulture.
One of the recurrent themes from my other compiler workshops is “can you debug it ?” , so in an attempt at getting that sorted I simply ended up running and writing tests , therefore closing the loop on that OpenJDK compiler dev-loop.
So in my series of hacking on the Java compiler, we will focus this session on adding simple syntax updates and explore Jtreg the unit/regression test harness for OpenJDK.
Steps
- Task 0 : setup environment and IDE for
- JTreg
- OpenJDK
- Task 1 : run an existing test suite
- Task 2 : syntax sugar support and testing it
for example, enhanced map syntax
Map capitals = {
"norway" : "oslo",
"sweden": "stockholm",
"morocco": "rabat",
"australia": "canberra,
}
- Task 3 : run the tests inside the IDE
- Task 4 : run the tests with a debugger attached
Full documentation will be provided
Necessary Tools
- GitHub account
- Java 20 / Java 21
- Docker (which would provide the required Java and Maven environment dependencies)
Takeaways
- Get some exposure to OpenJDK development loop
- Learn to navigate around OpenJDK project
