So DrJava searches for tools.jar (the library file containing the compiler in Java JDK distributions prior to Java 9) in common locations on Windows, Mac OS X, and Linux to find a compiler (more accurately, what were common locations in 2007).
I am running DrJava on JDK 8 and I faced the same issue when I ran DrJava Windows App. I now run DrJava jar file instead of windows app. This may also happen if you're trying to run your code which has been modified (accidently or otherwise) after your last compilation. Just compile it again (shift + F5) and run (keyboard - F2).
Other versions may of course work, but it seems Corretto 8 is the officially recommended version. From the DrJava web page: We strongly recommend installing the Amazon Corretto 8 distribution of Open JDK 8 available from the Amazon Corretto download page because this distribution appears to be the most comprehensive and best supported formulation of Open Java 8.

According to the DrJava documentations, the current beta version (drjava-beta-2019-220051 that's what did you download probably) is compatible with Java 8, which is the only supported version of "traditional" Java. Later versions of Java use a new package system and distribution format breaking compatibility with Java applications that access files in the underlying distribution.
According to the official site of the DrJava, they say that "The latest beta release of DrJava works transparently with OpenJDK 8 and OpenJRE 8 on all platforms"

Save this question. Show activity on this post. My IDE is DrJava, I am trying to open a previous project but I cant seem to get JDK 8 working. I wiped my computer so I've had to reinstall everything. But whenever I try to install JDK 8, which is what I coded my program in, it keeps saying I have 7.0_7 installed.
