Public bug reported:
(using Ubuntu 8.10 32bit and the packages sun-java6-bin and sun-
java6-jre)
Uninstalling sun-java6 (6-10-0ubuntu2) and then installing openjdk-6
(6b12-0ubuntu6.1) leads to some "warnings" regarding binfmts:
(from /var/log/apt/term.log -- sorry, its partly german, but that should not
matter)
-------------------
Richte openjdk-6-jre-headless ein (6b12-0ubuntu6.1) ...
Installiere neue Version der Konfigurationsdatei
/etc/java-6-openjdk/security/java.security ...
update-binfmts: warning: current package is openjdk-6, but binary format
already installed by sun-java6
-------------------
The reason for this error message: even after a complete uninstall of
sun-java6 I get:
-------------------
$ update-binfmts --display
jar (enabled):
package = sun-java6
type = magic
offset = 0
magic = PK\x03\x04
mask =
interpreter = /usr/lib/jvm/java-6-sun-1.6.0.10/jre/lib/jexec
detector =
-------------------
To get rid of the error message from update-binfmts I had to manually
remove that entry:
-------------------
$ update-binfmts --package sun-java6 --remove jar
/usr/lib/jvm/java-6-sun-1.6.0.10/jre/lib/jexec
update-binfmts: warning: no executable
/usr/lib/jvm/java-6-sun-1.6.0.10/jre/lib/jexec found, but continuing anyway as
you request
-------------------
After doing the above and installing openjdk-6 the binftms-entry for
"jar" is correct:
-------------------
$ update-binfmts --display
jar (enabled):
package = openjdk-6
type = magic
offset = 0
magic = PK\x03\x04
mask =
interpreter = /usr/bin/jexec
detector =
-------------------
But _without_ manual intervention (i.e. NOT running "update-binfmts
--package sun-java6 --remove jar
/usr/lib/jvm/java-6-sun-1.6.0.10/jre/lib/jexec") uninstalling sun-java6
and installing openjdk-6 leads to a wrong binfmts-entry:
-------------------
$ update-binfmts --display
jar (enabled):
package = sun-java6
type = magic
offset = 0
magic = PK\x03\x04
mask =
interpreter = /usr/lib/jvm/java-6-sun-1.6.0.10/jre/lib/jexec
detector =
-------------------
I think it is expected that uninstalling sun-java6 does remove its
binfmts-entry for "jar" automatically, so please include this behavior in the
package.
(oh, and uninstalling openjdk-6 doesn't remove its binfmts-entry either so that
must have been overlooked as well..)
