Quantum + Cucumber + TestNG: “TestStep implementation not found” happens randomly on different suites

[ShevyKossovsky]

Hi everyone, I'm capturing this issue here.

I'm working on a mobile automation framework using Perfecto Quantum, which integrates QAF + Cucumber (v1.2.5) + TestNG (v6.10).
Occasionally, and without any apparent reason, some test executions fail with the following error:
`

This happens randomly across different suites, even though:

• All steps are properly implemented.
• There is no duplication in method names.
• The step.provider.pkg property is correctly set.

It is not a problem of missing or misnamed steps — the same steps run successfully in other executions. The issue appears to be inconsistent and unpredictable.

I a'm using:

• Quantum version: 1.22.0
• Cucumber: 1.2.5
• TestNG: 6.10
• Execution method: Running testng.xml suites via .BAT files
• Shared config: Common env.properties file across all suites
• Step provider configuration:

  step.provider.pkg=com.quantum.steps
  
  
  
  

How can I solve it??
Thank everyone.
