Package: jtreg Version: 4.1-2 Severity: important While trying to compile the experimental openjdk-8 package from source, the jtreg test suite completely failed to run with the error message "Cannot determine version of java to run jtreg".
I found that the reason was that jtreg expects to find a usable JVM in /usr/lib/jvm/default-java/, unless $JAVA_HOME provides a different path. However, this default value will fail if default-jre-headless is not installed, as may well be the case (e.g., I had manually installed openjdk-7-jdk without any of the default-(jre|jdk)* packages). Without default-jre-headless: $ jtreg -version Cannot determine version of java to run jtreg With default-jre-headless: $ jtreg -version jtreg, version 4.1 src b02 Installed in /usr/share/java/jtreg.jar Running on platform version 1.6.0_31 from /usr/lib/jvm/java-6-openjdk-amd64/jre. Built with 1.6.0_18 on 07/07/2011 03:57 AM. Copyright 2008 Sun Microsystems, Inc. All Rights Reserved. Use is subject to license terms. Since jtreg can still be used without default-jre-headless by setting JAVA_HOME as appropriate, a "Depends" relationship is not warranted, but "Recommends" or "Suggests" seems reasonable. An alternative approach would be to simply use the first java binary found in $PATH by default, which will usually be whatever the administrator has selected using update-java-alternatives, which also seems reasonable. The problem also exists in sid (jtreg_4.1-b09-1), although the error message is more useful because it directly points at the missing java binary: $ jtreg -version /usr/bin/jtreg: 86: /usr/bin/jtreg: /usr/lib/jvm/default-java/bin/java: not found -- System Information: Debian Release: 7.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/32 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages jtreg depends on: ii javahelp2 2.0.05.ds1-6 ii libjtharness-java 4.4.0-MR1-Rel-b19-1 ii libxalan2-java 2.7.1-7+deb7u1 jtreg recommends no packages. jtreg suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
