I don't know if this might add to the discussion. I have tried build a simple Java application comprising 2 source files (Main.java and module-info.java) and have it call the default logger for Log4j2 V2.11.1 to output a single error message. Nothing more. I put the log4j-api-2.11.1.jar on the Modulepath as shown by Project Properties > Library > Compile tab.
Log4j2 V2.11.1 is a Multi-release JAR (MR-JAR). The module-info.class file is in log4j-api-2.11.1.jar under the folder META-INF/versions/9, which seems to match what the CachingFileManager expects at line 389. I am not sure if I am looking at all the right places. The Netbeans editor can see the module log4j.api because it appears in the drop-down menu of completion suggestions and does not have wiggly red line under it. My simple test program has a module-info.java file that requires log4j.api and nothing else. This bit definitely works as I would expect. The RMB Clean & Build function eventually generates an error pointing to the line *requires log4j.api* in my module-info.java. It generates this error even if I try to compile the module-info.java file on its own. It seems to me that the ant build script cannot find module but the Netbeans editor can. Unfortunately, I do not understand ant scripts enough to dig any deeper. I have tried building this program under JDK-9, JDK-10 and JDK-11. My Netbeans runs on JDK-10. I am learning how to migrate to modules by trial and error. I may have made an error, but if I have, I don't know where. I hope this is helpful.
