Abstract: An apparatus includes at least one processor executing a method for managing memory among a plurality of concurrently-running virtual machines, and a non-transitory memory device that stores a set of computer readable instructions for implementing and executing said memory management method. A memory optimization mechanism can reduce a memory usage of a virtual machine at a cost of increasing a central processing unit (CPU) usage. Information on a memory usage and a CPU usage of each virtual machine is periodically collected. When a first virtual machine exhibits high memory use, at least one second virtual machine with an extra CPU capacity is identified. A memory optimization mechanism is applied to the second virtual machine to reduce memory used by the second virtual machine, thereby providing a portion of freed memory that is then allocated to the first virtual machine.

Abstract: A method for executing native code in a distributed Java Virtual Machine (JVM) is disclosed herein. The method may include receiving, in a first thread executing in a remote execution container, a first native code-generated call, such as a Java Native Interface (JNI) call, to a second thread, the first call including a first array write request. The first call may be stored in an instruction cache and bundled with a second native code-generated call and sent to the second thread. The calls are unbundled and executed in the second thread. An opaque handle to an array returned by the second call is bundled with corresponding array data and returned to the first thread. The array data of the bundle is stored in a data cache and retrieved in response to requests for the array data addressed to the second thread. A corresponding computer program product is also disclosed.

Abstract: A method for providing control of Java resource runtime usage may include establishing communication with one or more Java virtual machines (JVMs) forming a hive via a hive communication channel where the hive comprises a plurality of JVMs configured to enable utilization of at least one shared resource, receiving, via the hive communication channel, environmental information indicative of hive activity relative to the at least one shared resource from at least one of the one or more JVMs, and adapting, via processing circuitry, operations associated with use of the at least one shared resource based on the environmental information.

Abstract: A method for running multiple copies of the same native code in a Java Virtual Machine is described. In one embodiment, such a method includes providing a class to enable segregating multiple copies of the same native code. The method defines, within the class, a native method configured to dispatch operation of the native code. The method further includes generating first and second instances of the class. Calling the native method in the first instance causes a first copy of the native code to run in a first remote execution container (e.g., a first process). Similarly, calling the native method in the second instance causes a second copy of the native code to run in a second remote execution container (e.g., a second process) separate from the first remote execution container. A corresponding computer program product is also disclosed.

Abstract: A method of optimizing the handling of throwables in a real-time compliant java virtual machine includes receiving a throwable generated within a first memory scope area when that scope is exited, traversing the Java stack to identify the application code where the received throwable will be, or should be, caught/handled during program execution, identifying a second memory scope area within the stack of memory scopes, the second memory scope area being the area which will be active during catching and handling of the received throwable, and propagating information from the received throwable to a new ThrowBoundaryError in the second memory scope area irrespective of the scopes between them.
