Config file not found exception disables PiranhaJava refactoring silently

I am trying the sample java gradle project and after running clean build piranha only removes the SAMPLE_STALE_FLAG enum but not the code checks. This is the output -

public class MyClass {

  enum TestExperimentName {
    //REMOVED FROM HERE BUT NOT BELOW
  }

  private XPTest expt;

  public void foo() {
    if (expt.flagEnabled(TestExperimentName.SAMPLE_STALE_FLAG)) {
      System.out.println("Hello World");
    }

  }

  public void bar() {
    if (expt.flagDisabled(TestExperimentName.SAMPLE_STALE_FLAG)) {
      System.out.println("Hi World");
    }
  }

  static class XPTest {
    public boolean flagEnabled(TestExperimentName x) {
      return true;
    }

    public boolean enableFlag(TestExperimentName x) {
      return true;
    }

    public boolean disableFlag(TestExperimentName x) {
      return true;
    }

    public boolean flagDisabled(TestExperimentName x) {
      return true;
    }
  }
}

Here is my gradle file - https://github.com/vihanparmar/testRepo/blob/master/test/build.gradle

Please let me know what i am doing wrong or if this is an issue.

I tried abosolute path too - options.errorprone.errorproneArgs.add("-XepOpt:Piranha:Config=Users/vparmar/Documents/GitHub/testRepo/test/config/properties.json") and

options.errorprone.errorproneArgs.add("-XepOpt:Piranha:Config=/Users/vparmar/Documents/GitHub/testRepo/test/config/properties.json") still no luck
