Misunderstood invariants when code is modified during maintenance Garden variety mistakes: typos, use of the wrong boolean operator FindBugs uses static analysis to inspect Java bytecode for occurrences of bug
1. How to fix the system Cannot find the path specified in Java? If you encounter the "system cannot find the path specified" error in Java, it usually means that the Java Virtual Machine (JVM) is unable to locate a file or folder that it needs to execute a particular Java program. ...
Garden variety mistakes: typos, use of the wrong boolean operator FindBugs uses static analysis to inspect Java bytecode for occurrences of bug patterns. We have found that FindBugs finds real errors in most Java software. Because its analysis is sometimes imprecise, FindBugs can report false wa...

4)FindBugs可检测的bug pattern举例:检测java programing中容易陷入的bug pattern,equals() 实现时的一般规约违反Null pointer的参照 ,Method的返回值的check遗漏 ,初始化前field的访问,Multi-thread的正确性, 同期化处理的矛盾, 无条件的wait(), Code的脆弱性 ,可以变更的静态object ,内部数列参照的return等 ...
Writing clean, organized code is not just about aesthetics; it significantly reduces the chance of errors. Keep methods short, focus on a single task, and avoid deeply nested structures. Clear and consistent code structure makes it easier to spot mistakes that could lead to the “Cannot find ...
由java.lang.Object.equals定义的合同(对象),FALSE将永远是比较的结果 在运行时错误。 4. UG_SYNC_SET_UNSYNC_GET 类型 必改项 描述 This class contains similarly-named get and set methods where the set method is synchronized and the get method is not. This may result in incorrect behavior at ru...
Review theXOR gateway conditionsto verify if they are set properly to provide at least one valid outgoing connection for the process. Some of the known mistakes users do is evaluating drools expressions (which are set at the gateways) based on process variables. Drools expressions work with facts...
Too often, companies run to cheap, inexperienced developers without understanding what goes into app development—only to face costly mistakes later. In this article, we’ll cover what to look for when in need of app development services and how to hire one. Why hire a professional app ...
