摘要： Memory segments are allocated for a classloader to store class information, such as by selecting an allocation approach based on classloader type. In a first approach, in response to each request, a segment having a fixed size is allocated. In a second approach, in response to a first request, a first segment having a size equal to an amount of memory needed to store information related to the request is allocated. In response to a second request, a second segment having a second size is allocated, and in response to a third request, a third segment having a third size greater than the second size is allocated. In a third approach, in response to the first request, a first segment having a first size is allocated. In response to a second request, a second segment having a second size greater than the first size is allocated.

摘要： A process for providing a simulated date and/or time to a time-sensitive application is disclosed herein. Such a process may include detecting the invocation of a time handler method configured to retrieve system time. Upon detecting the invocation, the contents of a call stack may be captured and analyzed to determine which requester method initiated the invocation. The process may then determine whether the requester method should receive a real or simulated system time. A real system time may be returned to the requester method in the event it should receive the real system time. A simulated system time may be returned to the requester method in the event it should receive the simulated system time. A corresponding apparatus and computer program product are also disclosed and claimed herein.
摘要翻译： 本文公开了向时间敏感应用提供模拟日期和/或时间的过程。 这样的过程可以包括检测被配置为检索系统时间的时间处理程序的调用。 在检测到调用时，可以捕获并分析调用堆栈的内容，以确定哪个请求方方法启动调用。 然后，该过程可以确定请求者方法是否应该接收真实或模拟的系统时间。 如果实际的系统时间可能会收到真正的系统时间，则可能会将真正的系统时间返回给请求者方法。 如果模拟的系统时间应该接收到仿真的系统时间，则模拟的系统时间可能会返回到请求者方法。 本文还公开并要求对应的装置和计算机程序产品。

摘要： A computer implemented method, apparatus, and computer usable program code for profiling an application. Data is collected for analyzing performance of the application using a device driver for a profiler in an operating system kernel in response to the application executing in a virtual machine. Data is stored in a buffer. A report is generated containing the data from the buffer in response to an event in the virtual machine, wherein the application is profiled using the report. Collection of the data is halted in response to the application terminating execution in the virtual machine.

摘要： Under the present invention, program code is examined (statically or dynamically) for characteristics indicative of a potential to generate multiple threads. If none are found, single threaded optimization(s) such as desynchronization, optimization of globals, etc., can be implemented. In addition, if the program code is later revealed to have the potential to generate multiple threads, the single threaded optimization(s) can be corrected to avoid incorrect execution.
摘要翻译： 在本发明的范围内，针对指示产生多个线程的潜力的特性，检查（静态地或动态地）程序代码。 如果没有找到，则可以实现单线程优化，例如去同步，全局变量优化等。 另外，如果稍后显示程序代码有可能生成多个线程，则可以纠正单线程优化以避免错误执行。

摘要： A method, apparatus, and computer instructions for referencing a constant pool. A determination is made as to whether a bytecode references the constant pool. A relative offset to the constant pool is identified for the bytecode, in response to the bytecode referencing the constant pool. The bytecode is then replaced with a new bytecode containing the relative offset. The relative offset is used to reference the constant pool.
