At the beginning of 2019, I wrote about the state of Java modularization. I took a sample of widespread libraries, and for each of them, I checked whether: It supports the module system i.e. it provides an automatic module name in the manifestIt’s a full-fledged module i.e. it provides a module-info The results were interesting. 14 out of those 29 libraries supported the module system, while 2 were modules in their own right.
