Thanks for the feedback.  I think it is of little value to support older versions of Java.  Thus closing the report.

updating java to 1.8 is quite simple and painless: download from java.com, unpack the (only ~80Mb) tarball, set JAVA_HOME. This fixes the build issue for me.

This is on RHEL 6.10 server.

Thank you for the bug report.  I do not think this is documentation error, thus adapting the title.  "ClassHelper.class" is to my knowledge some helper class for the Java-Interface.  The change might be related to


What system do you use?  Does it offer an opportunity for Java 8 or newer to be installed?  Java 7 is rather old https://en.wikipedia.org/wiki/Java_version_history

I am recently getting these errors:

  JAVAC    scripts/java/org/octave/ClassHelper.class
javac: invalid source release: 8
Usage: javac <options> <source files>
use -help for a list of possible options
make[2]: *** [scripts/java/org/octave/ClassHelper.class] Error 2

javac -version reports 1.7.0_241 on this system.
