             Summary: Ant java webapplication in Netbeans 10 and later won't debug
                 Key: NETBEANS-4988
                 URL: https://issues.apache.org/jira/browse/NETBEANS-4988
             Project: NetBeans
          Issue Type: Bug
          Components: debugger - Ant, serverplugins - Tomcat
    Affects Versions: 11.3, 10.0
         Environment: Windows 10 pro, OpenJDK11, Tomcat 9
            Reporter: Roy Damman


I have a Wicket java webapplication Ant project created in Netbeans 7.x. In the past the project has moved to Netbeans 8.2 and 9.0. I use currently the OpenJDK11. I can still build, run and debug the project in Netbeans 9. But in Netbeans 10 and later (11.3), the project won't run in Tomcat 9. I have searched for the cause and found out that the class files are changed or deleted on the first attempt to run or debug after a *clean and build*. All the innerclasses and anonymous classes (*$*.class) files in the projects *build directory* are deleted. Also the normal other class files were shrunked in size. After a *clean and build* command there is also a *war* file created in the *dist* directory. When I restore the class files in the *war* file to the *build* directory suddenly the project will run. In Netbeans 9 everything works normally with the same project and Ant file. Also the Tomcat installation and JDK is the same. Later I found out that the problem depends on the project settings. When settings _Project->Build->Compiling->Compile-on-Save_ and _Project->Run->Deploy-on-Save_ are switched off, you can debug the project with Tomcat and the problem doesn't occur. But then you don't have that options. I haven't checked if this a sole Ant problem or that Maven projects also are affected.
