    Abstract: A computer system includes multiple class loaders for loading program class files into the system. A constraint checking mechanism is provided wherein a first class file loaded by a first class loader makes a symbolic reference to a second class file loaded by a second class loader, the symbolic reference including a descriptor of a third class file. The constraint mechanism requires that the first and second class files agree on the identity of the third class file and stores a list of constraints as a set of asymmetric relationships between class loaders. Each stored constraint, for a class loader which loaded a class file that contains a symbolic reference to another class file, includes a first parameter denoting the class loader which loaded the class file to which the symbolic references is made; and a second parameter denoting a class file which is identified by a descriptor in said symbolic reference.

    Abstract: A method and system are provided for aspect scoping in a modularity runtime. The method includes declaring a set of aspects of a bundle as public aspects in a first aspect configuration file, and filtering the aspect configuration files imported by a bundle to the files from bundles on which the importing bundle has a dependency. The method includes declaring a set of aspects of a bundle as private aspects in a second aspect configuration file. At weaving of aspects at a bundle, the weaving includes: any aspects defined as private aspects; any aspects defined as public aspects; any imported aspects; and any first configuration files from exporting bundles are declared.

    Abstract: A virtual machine in an object-oriented system includes an interpreter. In order to provide trace information from a program about specific method calls, a user defines a selection of methods to be traced. As the program runs on the interpreter, it is determined, whether or not the method is included within the selection to be traced. For those methods included within the selection, trace information about the method call is outputted. A method block is associated with each method and is used by the interpreter to invoke the method. For each method within the user-defined selection, a flag is set within the method block associated with the method. The status of this flag is checked when the interpreter invokes a method, in order to determine whether or not the method is included within the selection.

    Abstract: A method of obtaining trace data with respect to a running software program includes accessing a method in a call stack, the call stack including a sequentially ordered list of methods called during the running of the software program. If the accessed method in the call stack falls between a minimum trace offset and a maximum trace offset where the minimum trace offset and the maximum trace offset define a trace window, obtaining trace data for the method and outputting it to an output stream which is then collected into a trace data storage. If the trace data in the trace data storage meets predetermined adaptation rules then changing the position in the call stack of at least one of the minimum trace offset and the maximum trace offset.
