I went from IA 2010 to 2013 and made no changes to any of my IA projects.

My installer on Solaris is failing when executing my custom code.

With this error message:

Frustrating part is this worked at 2010 and now fails at 2013. Other calls to the same jar file, but different class works.
It is just failing on this one class within this jar file.

This call is failing:
---------------------------
Path: EXTRACTS_DIR$\TSMinstall\ia\lib\COIExtension.jar
Class: com.ibm.ac.coi.ext.ia.plugin.COIProcessInventorySteps


This one works:
-----------------------ia_install_log.txt
Path: EXTRACTS_DIR$\TSMinstall\ia\lib\COIExtension.jar
com.ibm.ac.coi.ext.ia.plugin.COIPlanCreation


I have uploaded the install log with the LAX_DEBUG=true turned on.
