clebert suconic commented on ARTEMIS-732:
-----------------------------------------
(I mean.. if you (or anyone) want to fix it.. great.. but I would say we need
an adaptative script for this)..
The warning is ignorable.. but we should fix it.
> Need a 64-bit specific launching script

> Key: ARTEMIS-732
> URL: https://issues.apache.org/jira/browse/ARTEMIS-732
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 1.4.0
> Environment: Debian Linux 64-bit, OpenJDK 1.8.0.102
> Reporter: Jim Gomes
> Labels: easyfix
> Fix For: 1.5.0
>
> Attachments: artemis, artemis64
>
> Original Estimate: 1h
> Remaining Estimate: 1h

> The artemis launching script located in the bin folder needs to be split into
> two separate scripts: one for 32-bit, and one for 64-bit. The current script
> attempts (but fails) to be run-time adaptive. However, when running on a
> 64-bit environment, the following error is always displayed when it is run:
> {noformat}
> OpenJDK 64-Bit Server VM warning: You have loaded library
> /home/username/apache-artemis-1.4.0/bin/lib/linux-i686/libartemis-native-32.so
> which might have disabled stack guard. The VM will try to fix the stack guard
> now.
> It's highly recommended that you fix the library with 'execstack -c
> <libfile>', or link it with '-z noexecstack'
> {noformat}
> The problem is with the {{exec}} command-line, specifically the
> {{-Djava.library.path}} parameter. It combines both the 32-bit library path
> and the 64-bit library path, but it doesn't actually work. The script should
> be split into two separate scripts, one for 32-bit and one for 64-bit. All
> that is necessary is to modify the library path to be platform specific, and
> the error condition is resolved. I have attached modified script files
> (*{{artemis}}* and *{{artemis64}}*) that can be used depending on the
> run-time environment. Here are the key differences between the two scripts:
> {code:title=32-bit version}
> exec "$JAVACMD" $JAVA_ARGS $ARTEMIS_CLUSTER_PROPS \
> -classpath "$CLASSPATH" \
> -Dartemis.home="$ARTEMIS_HOME" \
> -Djava.library.path="$ARTEMIS_HOME/bin/lib/linux-i686" \
> $DEBUG_ARGS \
> org.apache.activemq.artemis.boot.Artemis "$@"}}
> {code}
> {code:title=64-bit version}
> exec "$JAVACMD" $JAVA_ARGS $ARTEMIS_CLUSTER_PROPS \
> -classpath "$CLASSPATH" \
> -Dartemis.home="$ARTEMIS_HOME" \
> -Djava.library.path="$ARTEMIS_HOME/bin/lib/linux-x86_64" \
> $DEBUG_ARGS \
> org.apache.activemq.artemis.boot.Artemis "$@"
> {code}
