Description

When we start Karaf with the karaf script on AIX we get the following error:

user@host:/apps/user/pache-karaf-2.3.1/bin> ./karaf
MAXDATA=0xB0000000@DSA
karaf: JAVA_HOME not set; results may vary
IBM J9 VM (build 2.6, JRE 1.7.0 AIX ppc64-64 20120322_106209 (JIT enabled, AOT enabled)

When we checked on the IBM site we found this article:
http://www-01.ibm.com/support/docview.wss?uid=swg1IV29784

If we look in the startup script we find:

    # For AIX, set an environment variable
    if $aix; then
         export LDR_CNTRL=MAXDATA=0xB0000000@DSA
         export IBM_JAVA_HEAPDUMP_TEXT=true
         echo $LDR_CNTRL
    fi

And the IBM article states that you should avoid using IBM_JAVA_HEAPDUMP_TEXT variable to not have that error message we've seen. The preferred mechanism for controlling the production of
Heapdumps is the JVM option: -Xdump:heap.
