      ADDITIONAL SYSTEM INFORMATION :
      java version "11.0.1" 2018-10-16 LTS
      Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
      Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)
      on Ubuntu 18.04 64 bit

      A DESCRIPTION OF THE PROBLEM :
      Observed this error while compiling one of my project using maven. An entire stack trace was of internal classes so I don't know how to reproduce. I had searched on google and this was already known issue but it was mentioned that this bug has been fixed in Java 11. Below is the StackTrace:

      Caused by: org.apache.maven.plugin.compiler.CompilationFailureException: Compilation failure
      An exception has occurred in the compiler (11.0.1). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.
