A system, method and computer program product for conducting questions and answers with deferred type evaluation based on any corpus of data. The method includes processing a query including waiting until a “Type” (i.e. a descriptor) is determined AND a candidate answer is provided; the Type is not required as part of a predetermined ontology but is only a lexical/grammatical item. Then, a search is conducted to look (search) for evidence that the candidate answer has the required LAT (e.g., as determined by a matching function that can leverage a parser, a semantic interpreter and/or a simple pattern matcher). In another embodiment, it may be attempted to match the LAT to a known Ontological Type and then look for a candidate answer up in an appropriate knowledge-base, database, and the like determined by that type. Then, all the evidence from all the different ways to determine that the candidate answer has the expected lexical answer type (LAT) is combined and one or more answers are delivered to a user.

For one embodiment, a computerized method for detecting exploit attacks on an interpreter comprises configuring a virtual machine including a user mode and a kernel mode and processing an object by an application operating in the user mode of the virtual machine. Responsive to the processing of the object, detecting a loading of an interpreter. Furthermore, responsive to the loading of the interpreter, inserting one or more intercept points for detecting one or more types of software calls from the interpreter or for detecting a certain type or certain types of activities occurring within the interpreter. Thereafter, an exploit attack is detected as being conducted by the object in response to the interpreter invoking a software call that corresponds to the one or more types of software calls that is considered anomalous when invoked by the interpreter or an anomalous activity being conducted within the interpreter.

A data processing system supports execution of both native instructions and Java bytecodes using a hardware executer for the Java bytecodes where possible and a software instruction interpreter for the Java bytecodes where these are not supported by the hardware. The sequences of native instructions 26 within the software instruction interpreter that perform the processing for the Java bytecodes being interpreted terminate within a sequence terminating instruction BXJ that acts differently depending upon whether or not an enabled hardware executer 6 is detected to be present. If an enabled hardware executer is detected as present, then the execution of the next Java bytecode is attempted with this. If an active hardware executer is not present, then the next Java bytecode is passed directly to the software instruction interpreter.

Methods, systems, and computer program products are provided for profiling source code to enable improved source code execution. A runtime engine includes a parser, a bytecode generator, an execution controller, an interpreter, a just-in-time (JIT) compiler, and a profile generator. The parser receives source code coded in a dynamic language and parses the source code to generate parsed source code. The bytecode generator converts the parsed source code to bytecode. The interpreter is configured to interpret the bytecode when enabled by the execution controller. The JIT compiler is configured to compile the bytecode when enabled by the execution controller. The profile generator generates profile information from the bytecode and stores the profile information. The execution controller enables the interpreter or the JIT compiler to perform their respective functions based on the profile information.
