Abstract: An approach is provided in which the approach collects distributed test results from multiple users, wherein at least one of the multiple users is an untrusted user. The approach aggregates the distributed test results in response to determining that each one of the distributed test results corresponds to the same system under test. The approach then presents the aggregated test results as a trusted test result.

Abstract: A method for executing an application in an application class library by an application launcher software component, the application launcher software component having associated a name, the method comprising the steps of: deriving a unique application class identifier from the name of the application launcher software component; and instantiating an application class having the application class identifier.

Abstract: Methods and systems for generating a hashcode for a hash table are provided to improve the hash table performance. A particular method includes receiving an input of a key; applying a hash function to the key to generate an incoming hashcode of the key; encoding a key type into the incoming hashcode to generate a first hashcode; and storing the first hashcode. A particular method includes encoding the key type into at least one bit of a bucket index portion of the incoming hashcode.

Abstract: The invention is directed to a method of replacing code in an object oriented application program running on a Virtual Machine (VM). The method comprises the steps of receiving at the virtual machine a request to replace code; in response to receipt of said request, examining each thread's call stack to determine if any thread includes a method that will be made obsolete by a proposed code replacement; and, if it is determined that there are no threads that include such a method in their call stacks, performing the code replacement. However, for a thread whose call stack is determined to include a method that will be made obsolete by the proposed code replacement, the method includes the step of allowing the thread to continue running until the thread unwinds past that method in its call stack and then suspending said thread. This comprises a part of a process of determining a safe state for code replacement. The invention is also directed to a method of initializing new variables in such replacement code.

Abstract: A method, apparatus and software for managing software component version identifications in a componentised software system in which one or more software components are arranged to export one or more application program interfaces (APIs). The system is arranged to derive meta data defining data structures for APIs exported by a software component and to identify any differences between the meta data and previously derived meta data for the same component so as to enable notification of any identified differences.
