Issue/Introduction:

Using 9.1.7 APM agent version of Tomcat and Java 1.5 on AIX 7 and higher, the APM agent works correctly.
but using 10.7 GA APM agent version (no HF or SP on top) with Java 1.5.x on AIX 7 (with agentnoredef) is not possible
the APM agent is not launching and therefore not logging.
