REST / JSON webapp - java.lang.ArrayIndexOutOfBoundsException：2560

Question

当我使用stream / lambda函数时，我在Apache Tomcat的REST / JSON Web应用程序中收到以下异常。我很困惑为什么会这样。

环境

• Windows 7
• Oracle JDK 1.8.0_25
• Tomcat 7.0.62
• 代码是使用java版本编译的＆＃34; 1.8.0_65＆＃34; （Ubuntu上的Java（TM）SE运行时环境（版本1.8.0_65-b17），Java HotSpot（TM）64位服务器VM（版本25.65-b01，混合模式））
• 杰克逊1.9.2和泽西岛1.17.1

可能的根本原因

我发现注释掉以下代码可以避免这个问题。但是当我重新放入代码时，我从未看到任何日志语句。我的try{}catch{}似乎毫无意义。

public static Statistics get(PolicyFile mainPolicy, List<PolicyFile> referencePolicies) throws Exception {
    try {
        Stream<BuildingBlock> matchingResults = mainPolicy.getBuildingBlocks().stream();
        long ruleCount = matchingResults.filter(b -> "Rule".equals(b.getType())).count();
        long policyCount = matchingResults.filter(b -> "Policy".equals(b.getType())).count();
        long policysetCount = matchingResults.filter(b -> "PolicySet".equals(b.getType())).count();
        long permitCount = matchingResults.filter(b -> b.getDecision()!=null && Result.DECISION_PERMIT==b.getDecision()).count();
        long denyCount = matchingResults.filter(b -> b.getDecision()!=null && Result.DECISION_DENY==b.getDecision()).count();
        return new Statistics(ruleCount, policyCount, policysetCount, permitCount, denyCount);

    } catch (Exception e) {
        throw new Exception("Cannot parse data", e);
    }
}
