Not able to generate a cucumber report when embed image is long

[kotharisandy]

After upgrading net.masterthought dependency to 5.8.2 the cucumber reporting through is notd generating reports when embedded image size is long

List<String> jsonFiles = new ArrayList();
    jsonFiles.add(cucumberFolder);
    String reportName = PropertyUtils.get(ConfigMap.REPORT_NAME) != null && !Objects.requireNonNull(PropertyUtils.get(ConfigMap.REPORT_NAME)).isEmpty() ? PropertyUtils.get(ConfigMap.REPORT_NAME) : "Cucumber Report";
    Configuration configuration = new Configuration(reportOutputDirectory, reportName);
    String envName = SessionInitiator.getInstance().getEnvironment();
    if (envName.equalsIgnoreCase("ode")) {
        envName = "ODE ( " + PropertyUtils.get(ConfigMap.NAME_SPACE) + " ) ";
    }
    String buildNumber = "1";
    configuration.setNotFailingStatuses(Collections.singleton(Status.SKIPPED));
    configuration.setBuildNumber(buildNumber);
    configuration.addClassifications("Environment Name ", envName);
    configuration.addClassifications("Automation Tag Name", PropertyUtils.get("cucumber.filter.tags") != null ? PropertyUtils.get("cucumber.filter.tags") : "");
    configuration.addClassifications("Run By :", PropertyUtils.get(ConfigMap.AUTOMATION_RUN_BY) != null ? PropertyUtils.get(ConfigMap.AUTOMATION_RUN_BY) : "");
    configuration.addClassifications("Platform", System.getProperty("os.name"));
    if (Objects.requireNonNull(PropertyUtils.get(ConfigMap.AUTOMATION_TYPE)).equalsIgnoreCase("MWEB") || Objects.requireNonNull(PropertyUtils.get(ConfigMap.AUTOMATION_TYPE)).equalsIgnoreCase("DWEB")) {
        configuration.addClassifications("Platform", SessionInitiator.getInstance().getBrowser());
    } else if (Objects.requireNonNull(PropertyUtils.get(ConfigMap.AUTOMATION_TYPE)).equalsIgnoreCase("APP")) {
        configuration.addClassifications("App Device Type", SessionInitiator.getInstance().getPlatformType());
    }
    configuration.addPresentationModes(PresentationMode.PARALLEL_TESTING);
    configuration.addPresentationModes(PresentationMode.EXPAND_ALL_STEPS);
    configuration.setQualifier("cucumber-report-1", "First report");


    try {
        ReportBuilder reportBuilder = new ReportBuilder(jsonFiles, configuration);
        Reportable result = reportBuilder.generateReports();
    } catch (Exception e) {

    }

Getting below errror message after generating report from above code

[damianszczepanik]

This is not an issue with plugin upgrade - this is limitation, probably with memory

[gitissuepost]

@damianszczepanik - I seldom see this issue even with a high config machine with memory of around 32G and i am still on plugin version 5.7.7. However, we have few other reporter plugins dependent on the same json files, were able to generate the html reports without any exception.
