Hello,
I am a students trying to learn Java, and I came across DrJava. It was exactly what I needed, but it only worked once. I compiled and ran a simple code (a classic HelloWorld code), and it worked. I closed DeJava, but when I tried to reopen it, I saw an error. This is the error text:

This is the exact code I used:

/**
 * The HelloWorldApp class implements an application that
 * simply prints "Hello World!" to standard output.
 */
class HelloWorldApp {
    public static void main(String[] args) {
        System.out.println("Hello World!"); // Display the string.
    }
}

In your traceback, references to the Eclipse Compiler appear which
surprised me. I have not tested the Eclipse Compiler in recent generations
of DrJava (going back nearly a decade); in fact, DrJava typically does not
"find" the Eclipse compiler when I run DrJava on my machine. We do not use
the Eclipse Compiler in DrJava because DrJava can almost always find the
official Oracle Java compiler assuming that a Java 8 JDK rather than a Java
8 JRE (a subset of the JDK that EXCLUDES the compiler) has been installed.
We added the EclipseCompiler to DrJava years ago because it is open source
and sufficed as a compiler when DrJava is run on a machine with no Java JDK
installed. The addition of the Eclipse compiler to DrJava predates the
existence of reliable versions of javac in "openjava" which we arguably
should use instead.

Make sure that you have installed a JDK distribution of Oracle Java 8 and
select the compiler "JDK 8.0-oracle" in the menu at the extreme right of
the "Compiler Output" tab in the lower section of DrJava window. I can
make my latest build of DrJava available to you if you would like. The
javac compiler in the Oracle JDK distribution is not open source so we
cannot include it as part of DrJava.
