[duplicate] up vote 204 down vote favorite 37 This question already stackoverflowerror java recursion has an answer here: What is a StackOverflowError? 11 answers I've looked everywhere and can't find a solid answer. According to the documentation, Java throws a java.lang.StackOverflowError error under the following circumstance: Thrown when a stack overflow occurs because an application recurses too deeply. But this raises two questions: Aren't there other ways for a stack overflow to occur, not only through recursion? Does the StackOverflowError happen before the JVM actually overflows

the stack or after? To elaborate on the second question: When Java throws the StackOverflowError, can you safely assume that the stack did not write into the heap? If you shrink the size of the stack or heap in a try/catch on a function that throws a stack overflow, can you continue working? Is this documented anywhere? Answers I am not looking for: A StackOverflow happens because of bad recursion. A StackOverflow happens when the heap meets the stack. java jvm stack-overflow share|improve this question edited Mar 4 '14 at 21:54 hichris123 6,551113257 asked Mar 4 '14 at 20:46 retrohacker 1,66231025 marked as duplicate by Jarrod Robersonjava Users with the java badge can single-handedly close java questions as duplicates and reopen them as needed.

That makes it unlikely to produce a stack overflow without recursion. –nosid Mar 4 '14 at 20:49 1 You could produce a gigantic chain of metho

My Publications Saturday, July 4, 2009 Diagnosing and Resolving StackOverflowError A recent JavaWorld Community forum message (Stack Overflow after instantiating new object) reminded me that the basics of the StackOverflowError are not always understood well http://marxsoftware.blogspot.com/2009/07/diagnosing-and-resolving.html by people new to Java. Fortunately, the StackOverflowError is one of the easier http://www.ibm.com/support/docview.wss?uid=swg21162896 of the runtime errors to debug and in this blog posting I will demonstrate how easy it often is to diagnose a StackOverflowError. Note that the potential for stack overflow is not limited to Java.Diagnosing the cause of a StackOverflowError can be fairly straightfoward if the code has been compiled with overflow error the debug option turned on so that line numbers are available in the resulting stack trace. In such cases, it is typically simply a matter of finding the repeating pattern of line numbers in the stack trace. The pattern of repeating line numbers is helpful because a StackOverflowError is often caused by unterminated recursion. The repeating line numbers indicate the code that is being stack overflow error directly or indirectly recursively called. Note that there are situations other than unbounded recursion in which a stack overflow might occur, but this blog posting is limited to StackOverflowError caused by unbounded recursion.The relationship of recursion gone bad to StackOverflowError is noted in the Javadoc description for StackOverflowError that states that this Error is "Thrown when a stack overflow occurs because an application recurses too deeply." It is significant that StackOverflowError ends with the word Error and is an Error (extends java.lang.Error via java.lang.VirtualMachineError) rather than a checked or runtime Exception. The difference is significant. The Error and Exception are each a specialized Throwable, but their intended handling is quite different. The Java Tutorial points out that Errors are typically external to the Java application and thus normally cannot and should not be caught or handled by the application.I will demonstrate running into StackOverflowError via unbounded recursion with three different examples. The code used for these examples is contained in three classes, the first of which (and the main class) is shown next. I list all three classes in their entirety because line numbers are significant when debugging the StackOverflowError.StackOverflowErrorDemonstrat
recursion; recursively; jit; JustInTime; Hot; Spot; WebSphere; Just-In-Time Technote (troubleshooting) Problem(Abstract) Stack Overflow exceptions can occur when a thread stack continues to grow in size until reaching the maximum limit. Symptom A stack overflow can result from: A deeply nested application An infinite loop within an application A problem in just-in-time (JIT) compiled code Applications requiring a larger stack size, especially ones relying on XML, GUI, or java2D classes. Native method calls Stack overflow issues are frequently masked by Out of Memory exceptions. By resolving the memory constraints, the stack overflow can be resolved. Cause When a stack overflow occurs, the amount of stack space required by the program exceeds what is configured for the stack in the Java™ Virtual Machine (JVM) process, or the native stack size configured by the operating system. Some applications require stacks that are larger than the default size; for example, a graphics-intensive Java program can require a larger stack, which may require an increase in the stack size to avoid StackOverflow. Diagnosing the problem Look for either Out of Memory messages or java.lang.StackOverflow in the server logs. The process may continue to run after either of these messages are seen. If a crash did occur, a javacore should have generated on IBM SDK. You will either see the signal as SIGSEGV, SIGILL, SIGABRT, or SIGBUS. Usually the current thread will indicate the following pending=java.lang.StackOverflowError Resolving the problem Explanations and Solutions Detailed Configuration Options Explanations and Solutions Infinite Recursion If an application is performing recursion, the maximum stack size can easily be reached and a Stack Overflow exception is thrown. The thread stack has a limited size and eventually its space will run out as the thread stack grows without bounds. Some traits of recursion: - Large thread stacks that appear to repeat - An infinite loop that continuously spawns off threads - Very large XML documents loaded into the Document Object Model (DOM) - JSP or servlets calling itself (usually by executing forward or include to itself) - Repeated calls in native functions Increasing the thread stack size allows for larger thread stacks. However if the recursion continues to trigger a stack overflow, the next step is to identify what code is causing the recursion from
