Subject ACTIVEMQ_CLASSPATH
Date Fri, 31 Jul 2015 18:59:57 GMT
Hello,
ActiveMQ 5.8.0 has been running in our environment (RHEL 5.0) for many
years.  We have a wrapper script that sets up some environment variables
before launching ActiveMQ, including setting ACTIVEMQ_CLASSPATH to allow our
SSL classes to find and load our keystores.  Although we are running on
Linux, I found that I needed to set the ACTIVEMQ_CLASSPATH using
Windows-style class pathSeparator.  That is:

ACTIVEMQ_CLASSPATH="$MYHOME;$MYHOME/classes;$MYHOME/classes/mycompany.jar";
export ACTIVEMQ_CLASSPATH

Instead of:
ACTIVEMQ_CLASSPATH="$MYHOME:$MYHOME/classes:$MYHOME/classes/mycompany.jar";
export ACTIVEMQ_CLASSPATH

If I used the Unix-style pathSeparator, then ActiveMQ would fail to start
because it could not find my classes in mycompany.jar file, but with the
Windows-style pathSeparator, it works, even though it is running on Linux!

Flash forward to today when I am experimenting with ActiveMQ 5.11.1 upgrade. 
Suddenly the broker won't start because it can't find my properties files
that are in the classpath.  I traced it back to this change in the
'bin/activemq' script in the distribution.

ActiveMQ 5.8.0 implementation (in fact this is true thru 5.10.2):
ACTIVEMQ_CLASSPATH="${ACTIVEMQ_CONF};${ACTIVEMQ_CLASSPATH}"

Notice the Windows-style pathSeparator.  This works perfectly.

However, beginning with ActiveMQ 5.11.0, the above line looks like:

ACTIVEMQ_CLASSPATH="${ACTIVEMQ_CONF}:${ACTIVEMQ_CLASSPATH}"

Here it has been "fixed" to use the Unix-style separator, but this actually
breaks it!  If I change this one thing back to ";", then all is well again.

Has anyone else seen this problem?  Why does ActiveMQ want Windows style
pathSeparator on Linux?  Should I file a bug?

Thanks,
Greg Rabil
