Mac + OpenJDK8 + drjava-20190813-220051 not compiling

Norm Krumpe — Tue, 20 Aug 2019 18:36:02 -0000

I was optimistic that the new beta of Dr. Java would resolve Mac issues, but I am running into problems with getting code to compile.

Tested on multiple Macs, I am finding that the latest beta is not successfully compiling for me. The steps that lead to my problem:
1. Create a new Java class.
2. Save and compile. The Compiler is JDK 8.0_222 (and no other compilers show as available). The message back is "Compilation completed." BUT...
3. Try to run and the message is "Current document is out of sync with the Interactions Pane and should be recompiled!" When I look, it turns out that no .class file was ever actually created.

I can, in a terminal window, compile and run the file. After compiling from the command line, Dr. Java is able to run the code in my .class file. So, the issue seems to be that the call to the compiler from within Dr. Java is not working.

Possibly helpful: When I look at Dr. Java's Console pane, I see:
"Compiler is using classPath = '[/Users/easguest, /Applications/DrJava.app/Contents/MacOS/drjava-beta-20190813-220051.jar]'; bootClassPath = 'null'
Fatal Error: Unable to find package java.lang in classpath or bootclasspath

In Preferences, under "Resource Locations", everything is blank.

Thank you for any information you can suggest.
