The exact amount of memory your particular application can use is specified during application startup. To make things more complex, Java memory is separated into different regions which can be seen in the following permgen java figure: The size of all those regions, including the permgen area, is set during the JVM launch. If you do not set the sizes yourself, platform-specific defaults will be used. The java.lang.OutOfMemoryError: PermGen space message indicates that the Permanent Generation's area in memory is exhausted. What is causing it?To understand the cause for the java.lang.OutOfMemoryError: PermGen space, we would need to understand what this specific memory area is used for. For practical purposes, the permanent generation consists mostly of class declarations loaded and stored into PermGen. This includes the name and fields of the class, methods with the method bytecode, constant pool information, object arrays and type arrays associated with a class and Just In Time compiler optimizations. From the above definition you can deduce that the PermGen size requirements depend both on the number of classes loaded as well as the size of such class declarations. Therefore we can say that the main cause for the java.lang.OutOfMemoryError: PermGen space is that either too many classes or too big classes are loaded to the permanent generation. Solution to the problem See how Plumbr's automatic root cause detection helps. Try plumbr Give me an exampleMinimalistic example As we described above, PermGen space usage is strongly correlated with the number of classes loaded into the JVM. The following code serves as the most straightforward example: import javassist.Cl

Note: Oracle Java 8 does not have a separate permanent generation space any more. The -XX:(Max)PermSize option makes no difference (the JVM will ignore it, so it can still be present). If you see java.lang.OutOfMemoryError: PermGen space errors, you need to increase the permanent generation space available to Eclipse. PermGen is the permanent generation of objects in the VM (Class names, internalized strings, objects that will never get garbage-collected). An easy, if somewhat memory-hungry fix is to enlarge the maximum space for these objects by adding -XX:MaxPermSize=128M as an argument to the JVM when starting Eclipse. The recommended way to do this is via your eclipse.ini file. Alternatively, you can invoke the Eclipse executable with command-line arguments directly, as in eclipse [normal arguments] -vmargs -XX:PermSize=64M -XX:Ma
