问题 I do not have access to the JVM settings since I am submitting code to be run elsewhere, so I can't follow the other Stack Overflow answers about extending stack size. Is there any way to do it from inside my Java file? The reason I want to do this (not really important): I am using recursion on a tree with 10^5 nodes. The average case is ok, but there is no guarantee on the shape of the tree. I am dealing with an edge case where the tree is just one long line. I get a StackOverflowError, but

问题 What does the java option -XX:-EliminateAllocations do? I couldn't find any documentation about it. 回答1: This key disables "Scalar replacement optimization" Simply spoken when an object is identified as non-escaping the JVM can replace its allocation on the heap with an allocation of its members on the stack which mitigates the lack of user guided stack allocation. The optimization is enabled by default since JDK 6U23 in the hotspot server compiler. More info. 回答2: HotSpot JIT does eliminate

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: JVM Options List - still being maintained post Oracle? Is there a page anywhere with a definitive complete list of the command line options available to run a JVM? Everywhere I look I get referred to http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html which is woefully incomplete. Even the Oracle page on Java 7 just refers to the page above. Apologies for such a basic question, but I

问题 I am trying to pass multiple parameters when I start tomcat through startup.bat . I tried adding these lines at the top of startup.bat file, however they do not work. set JAVA_OPTS="-Dapplication.home=E:\\webapp -Dfilepath=D:\\newFolder\\conf\\con.properties" Initially I was running the application with just one parameter -Dapplication.home=E:\\webapp which worked fine. Now I need to pass another parameter and this method fails. Please advice. On running, I get this exception a

问题 Is there any way of launching Oracle's Java.exe and have it take its command line options from a text file on Windows? What I'd like to be able to do is something like this: java.exe -optionsFile=myOptionsFile.txt MyClass where 'myOptionsFile.txt' contains a list of standard Java VM options such as "-classpath="my very long classpath" and "-Dthis=that" etc. All of the options must be present when Java.exe is run as it is the target of a memory debugging tool called VMMap. VMMap allows you to
