摘要： Apparatus, methods, and computer program products are disclosed for a process of terminating a thread in a clean, certain, and forcible manner. A thread is forcibly terminated in such a manner that data structures in the system are not left in an inconsistent state and the overall system status is not damaged. The methods and systems described are for terminating a thread in a computer language execution environment. Methods are implemented in an interpretive loop executing in a language that is interpreted and in runtime support libraries in a language that are not interpreted. A method of forcibly terminating a thread in a computer language execution environment is described. A thread receives a terminate thread command. The thread has associated with it a termination flag, a value of the termination flag being immutable once set, and one or more monitors. The termination flag is then set for the thread. An exception is then propagated in the execution environment thereby indicating termination of the thread. The exception handler and the finally clause of the thread is ignored during thread termination. The monitors associated with the thread are then exited.

摘要： Disclosed is a method for executing a remote method (200). Each argument of the remote method is wrapped when the argument is a remote object (202) (e.g., the argument's declared class implements a remote marker interface). However, each argument of the remote method is copied when an argument is not a remote object (202). The remote method is invoked using the wrapped or copied argument(s) (210) (e.g., the wrapped or copied arguments are passed to the invoked method). A result of the invoked remote method is then wrapped (e.g., prior to being passed to the process that is receiving the result) when the result is a remote object (216) (e.g., the result's declared class does not implement the remote marker interface). In contrast, the result of the remote method is copied (e.g., the copy is then passed to the process that is receiving the result) when the result is are remote object (216).

摘要： Disclosed are methods and apparatus for managing resources. In general terms, a resource manager (102) manages resource consumption (110) of several resource entities (106 and 108) which are each capable of consuming resources. The resource manager tracks the availability of such resources (210) and determines whether a resource is critically short or reaches a particular usage level (212). When a resource becomes critically short or reaches a particular usage level, the resource manager selects one or more resource entities based on one or more criteria (214). For example, a resource entity which has the least restrictive resource usage policy or state is selected. The resource manager then requests that the selected resource entity changes its resource usage state to a more restrictive state (304). Of course, when resource usage reaches an acceptable level, the resource manager may also inform each resource entity (or previously selected resource entities) that they may set their resource consumption state to a less restrictive state (314).

摘要： Techniques for processing native events associated with tasks that are concurrently supported in a virtual machine are disclosed. The techniques allow the user of a virtual machine to concurrently perform tasks even if these tasks require processing of platform-specific (or native) events (e.g., platform- specific input). A smart event-dispatcher is used to dispatch native events to multiple tasks that are concurrently supported by the virtual machine. The smart event-dispatcher can determine which one of a plurality of concurrent tasks should receive the native event for processing. The determination can be made based on a variety of different criteria. In mobile devices, the foreground task is typically the only task that is displayed for the user of mobile devices at any given time. Thus, dispatching events to the foreground task is especially useful for a virtual machine that support a mobile device.
