#978 please help

I don't have enough informatoin to understand the bug. You are using an old version of DrJava (built in 201) with problematic support for Java 7 and 8, and an Oracle Java 7 JVM that is no longer supported. If you can replicate the bug running Amazon Corretto JDK 8 Java distribution and the latest version of DrJava available from www.cs.rice.edu/~javaplt/drjavarice, I will look at it and see if I can fix it.

please help
