There are several key advantages of writing a compiler in Java. First of all, safety, meaning no crashes but exceptions instead and no real memory leaks. Furthermore, we’ll have a good IDE support and we’ll be able to use debuggers or profilers or other convenient tools. Also, the co...
Hi everyone, we are pleased to announce partial support of Javac as the underlying compiler in Visual Studio Code Java, JDT, and JDT-LS. The effort to provide this support has been a joint collaboration with Red Hat and Microsoft and is nearly a year in the making. This change aims to...
In the Java language, most method invocations arevirtual(potentially polymorphic), and are more frequently used than in C++. This means not only that method invocation performance is more dominant, but also that static compiler optimizations (especially global optimizations such as inlining) are much...
