JDK-8043516 : After "ulimit -v", the JVM can not start without extra GC command line args. To specify the number of CPUs for Java to use, add to the above commands: " -XX:ActiveProcessorCount=1" (where "1" is the number of CPUs you have reserved for your job. Setenv _JAVA_OPTIONS "-Xmx2048m -XX:CompressedClassSpaceSize=256m"Ī similar problem results from the Java JRE not correctly detecting the number of CPUs available. Setenv JAVA_OPTS "-Xmx2048m -XX:CompressedClassSpaceSize=256m" To fix the error " Unable to allocate bitmaps for parallel garbage collection for the requested heap", you may either reduce one of the memory allocations litsted above (heap, or compressed class metadata) - or you can turn off parallel garbage collection to save memory at the cost of some performance by adding the option "-XX:+UseSerialGC".įor example, to restrict the Java JRE heap memory allocation to a maximum size of 2GB and the class metadata to a size of 256MB, to run within a 4GB memory reservation, set the variables as follows:Įxport JAVA_OPTS="-Xmx2048m -XX:CompressedClassSpaceSize=256m"Įxport _JAVA_OPTIONS="-Xmx2048m -XX:CompressedClassSpaceSize=256m" To fix the error " Could not allocate metaspace", add the options "-XX:CompressedClassSpaceSize=m" to set the size of the class metadata memory allocation. I then compiled and ran it using Java 11 on a 12-core machine with some different options: Show the version of Java in use java -version openjdk version '11.0.6' OpenJDK Runtime Environment (build 11.0.6+10) OpenJDK 64-Bit Server VM (build 11.0.6+10, mixed mode) Run with defaults java -cp. This must be set large enough to accommodate loading your application into memory, but smaller than your requested total memory allocation by 2GB. To fix the error " Could not reserve enough space for object heap", add the options "-Xmxm" to set the maximum size for the object heap memory allocation. JDK-8073331 TESTBUG Test for VM option file feature (VM options specified in file). Or, for a Batch job, you can create a shell script that sets these values first and then afterward runs your java app. You can set these values and run your java app from within a single interactive RCE Powered Shell. These values must be set within the shell that launches your java application (i.e. To correct this behavior, you can set the shell environment variables JAVA_OPTS and _JAVA_OPTIONS before launching your java application. "Unable to allocate bitmaps for parallel garbage collection for the requested heap" "Could not reserve enough space for object heap" This will typically result in one of the following errors: The Java JRE is not aware of the resource limit you have set, and will try (and fail) to grab as much of the system memory as is free. Translation of the first screenshot of the middle screen: "To run 'Minecraft', you will nee Java SE 6-Runtime.When running an RCE Powered Application - for example an RCE Shell - you have the opportunity to reserve a requested amount of system memory. But using my workarround you will boot it Java SE 7 (depending on the standard Java version on the Mac) #Atlauncher java hotspot vm install#
If you do install Java SE 6 and start the launcher, it will use Java SE 6. There is a workarround to start the game with Java 7, what you do is this:Ģ.) cd /Applications (to the location of the launcher)ģ.) java -d64 -Xmx1024M -jar Minecraft.app/Contents/Resources/Java/Bootstrap.jar (as which -d64 forces it open 64 bits)Īnd then the launcher will start with Java SE 7

The installation path of Java on my mac is: /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home I installed Java 7 on my Mac but the launcher still does not recognizes the Java install. /Library/Internet Plug-Ins/ugin/Contents/Home/bin/java.With the JRE 7 or 8 installed, the launcher can launch the game using it, by changing the Executable in the Edit Profile menu to the following:
