We are using the Micro Focus plugin to run a single UFT test in an ALM test set. This worked fine in previous versions of the plugin, but not in version 5.7.

A popup on the agent (WerFault.exe, child of HpToolsLauncher.exe) shows:

HpToolsLauncher has stopped working

 

A problem caused the program to stop working correctly.

Please close the program.

The Jenkins build log shows:

The final line (Finished: SUCCESS) is only shown after closing the popup.

Aborting the test instead of closing the popup works:

I've also tried the following:

• Running with a timeout (the timeout is displayed in output instead of -1, but still crashes. Presumably the timeout only applies when it runs the test.)
• Specify a test set instead of a single test instance (no change - still crashes)

When we downgrade the plugin to version 5.6.2 the job successfully runs the test.
