Environment

All supported DevTest environments

Cause

The UFT properties listed below were added to environment variable properties and these properties will interfere with the DEVTEST start up script. They need to be in its own start-up script and not in the ENV Variables.. 

JAVA_OPTIONS=-Xbootclasspath/a:"C:\Program Files (x86)\HP\Unified Functional Testing\bin\java_shared\classes\jasmine.jar"

IBM_JAVA_OPTIONS=-Xbootclasspath/a:"C:\Program Files (x86)\HP\Unified Functional Testing\bin\java_shared\classes\jasmine.jar"

JAVA_TOOL_OPTIONS=-agentlib:jvmhook

Resolution

Option 1: 

Delete these environment variables, 
JAVA_OPTIONS
IBM_JAVA_OPTIONS
JAVA_TOOL_OPTIONS

Option 2:
