Skipped breakpoint because it happened inside debugger evaluation - Intellij IDEA

When I try to pick a breakpoint on any executive line of any method of my project, and I know that this method should be invoked for example 4 times, Intellij skips this breakpoint for 3 times and stops only on the last invocation. Method example (Endpoint class):

    @PayloadRoot(localPart = "getRelatedCIs", namespace = "http://www.projectname.com/ws")
public GetRelatedCIsResponse getRelatedCIs(GetRelatedCIs request) throws DataAccessException, WebServiceException {
    GetRelatedCIsResponse response = new GetRelatedCIsResponse();
    PageData page = request.getPageData();
    List<ConfigItemReference> ciRefs = translateCiRefList(request.getCiRef());
    RelatedCiResult relatedCis = configItemService.getRelatedCis(ciRefs, request.getRequestedType(),
            new Page(page.getPageNumber(), page.getPageSize(), page.getTotal()), request.getSort());
    response.getCis().addAll(relatedCis.getCis());
    page.setTotal(relatedCis.getPageInfo().getTotal());
    page.setPageSize(relatedCis.getPageInfo().getPageSize());
    response.setPageData(page);
    System.out.println("****************************INVOCATION***************************" + request.getRequestedType());
    return response;
}

Breakpoint is picked on the first line of the method. When program is stopped, there are already printed in console 3 lines ****************************INVOCATION***************************

In the left bottom part of the screen appears green notification:

Skipped breakpoint at %code reference% because it happened inside debugger evaluation

But I don't use any Evaluate Expression functionality when I perform debugging. Also there are my VM options of Run/Debug Configurations:

-XX:MaxPermSize=512m 
-Xms256m 
-Xmx1024m 
-Dcom.sun.management.jmxremote=true 
-Dcom.sun.management.jmxremote.port=9004 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false

The problem is described in IDEA-43728 and in the breakpoints documentation.

In short, to avoid it use suspend thread (not all) breakpoint policy.

Selecting the below checkbox helped me to minimize this error frequency. "Settings | Build, Execution, Deployment | Debugger | Stepping - Resume only the current thread" (as per suggestion in a fix https://youtrack.jetbrains.com/issue/IDEA-43728)
