Exception handling

A system comprising:

• a processing unit;
• and
• a memory coupled to the processing unit and storing instructions thereon, the instructions, when executed by the processing unit, performing actions comprising:
• in response to an application throwing an exception, detecting a target stack frame for handling the exception from a call stack of the application, wherein the call stack comprises a plurality of stack frames, and wherein detecting the target stack frame comprises determining whether to perform a search of the call stack based on whether one of the plurality of stack frames supports a one-phase exception handling mechanism or a two-phase exception handling mechanism;
• in response to determining that at least one of the plurality of stack frames supports the two-phase exception handling mechanism, performing a search on the call stack for
• a first stack frame supporting the two-phase exception handling mechanism and capable of handling the exception, and
• a second stack frame supporting the one-phase exception handling mechanism;
• and
• in response to the target stack frame being detected from the call stack, causing the target stack frame to handle the exception.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• in response to an application throwing an exception, detecting a target stack frame for handling the exception from a call stack of the application, wherein the call stack comprises a plurality of stack frames, and wherein detecting the target stack frame comprises determining whether to perform a search of the call stack based on whether one of the plurality of stack frames supports a one-phase exception handling mechanism or a two-phase exception handling mechanism;
• in response to determining that at least one of the plurality of stack frames supports the two-phase exception handling mechanism, performing a search on the call stack for
• a first stack frame supporting the two-phase exception handling mechanism and capable of handling the exception, and
• a second stack frame supporting the one-phase exception handling mechanism;
• and
• in response to the target stack frame being detected from the call stack, causing the target stack frame to handle the exception.
