Package: openjdk-6 Severity: normal
Java uses 1/4 ( MaxRAMFraction [1]) of the _physical_ memory as heap (Arguments::set_heap_size() [2]). If there is any limit pushing java below this, for example a ulimit, it will fail. The failure could also be cause in a virtualised situation for example using OpenVZ where the kernel will report the total memory, but the partition has a limit of less than 1/4 of that. The only reasonable workaround is to pass the "-Xmx" option whenever you run Java, but this isn't set when installing the openjdk-6-jre-headless package, so even setting that package up can fail with: Could not create the Java virtual machine. Error occurred during initialization of VM Could not reserve enough space for object heap I'm not sure of the best course of action to solve this - it seems like the nicest thing would be to look at the limit using the ulimit interface and reduce the default to a bit less than that (to allow for things other than the heap itself).
