In the message you sent me privately, the logs were:

467. java.at:367: testing Calculator  ...
./java.at:367: bison -fno-caret -o Calc.java Calc.y
./java.at:367: $SHELL ../../../javacomp.sh Calc.java
stderr:
warning: [options] bootstrap class path not set in conjunction with -source 1.3
error: Source option 1.3 is no longer supported. Use 1.6 or later.
error: Target option 1.4 is no longer supported. Use 1.6 or later.
stdout:
./java.at:367: exit code was 2, expected 0
467. java.at:367: 467. Calculator  (java.at:367): FAILED (java.at:367)

And config.log reads:

| configure:38553: checking for Java compiler
| configure:38799: found /usr/bin/javac
| configure:38945: javac -d . conftest.java
| configure:38974: javac -target 1.4 -d . conftest.java
| javac: target release 1.4 conflicts with default source release 1.8
| configure:39003: javac -target 1.4 -source 1.3 -d . conftest.java
| warning: [options] bootstrap class path not set in conjunction with -source 
1.3

-Xlint:-options.
| 4 warnings
| configure:39040: result: javac -target 1.4 -source 1.3


So we have two problems:
- in configure it’s only a warning, in the testsuite
  it’s a failure, why?
- our requirements are no longer valid on OSX 10.14, but
  can we really just move forward to 1.6?  To answer this
  question, I would need to ask the gnulib people, who provided
  us with these tests.
