Package: octave
Version: 4.4.1-5
Severity: normal
Dear Maintainer,
I don't know whether this is a bug in Octave or a bug in OpenJDK (or
both), but if an Octave program loads a Java library that creates a
subprocess, it results in an unhandled StackOverflowError, and trying
to get the exit status of the subprocess causes the entire program to
hang.
On Debian stretch (octave 4.0.3-3, openjdk-8-jre 8u252-b09-1~deb9u1):
$ octave -W -q -f
octave:1> b = javaObject('java.lang.ProcessBuilder', {'/bin/true'});
octave:2> p = b.start();
octave:3> p.waitFor()
ans = 0
On Debian buster (octave 4.4.1-5, openjdk-11-jre 11.0.7+10-3~deb10u1):
$ octave -W -q -f
octave:1> b = javaObject('java.lang.ProcessBuilder', {'/bin/true'});
OpenJDK 64-Bit Server VM warning: Archived non-system classes are disabled
because the java.system.class.loader property is specified (value =
"org.octave.OctClassLoader"). To use archived non-system classes, this property
must be not be set
octave:2> p = b.start();
Exception: java.lang.StackOverflowError thrown from the
UncaughtExceptionHandler in thread "process reaper"
octave:3> p.waitFor()
causes octave to hang.
(I have no idea what the "Archived non-system classes are disabled"
thing means, but it appears unrelated.)
