private Cache
resolveExceptionCache(CacheOperationInvocationContext<CacheResultOperation> context)

private static CacheOperationInvoker.ThrowableWrapper

Returns:

a clone exception with a rewritten call stack composed of the current call stack up to (included) the common ancestor specified by the className and methodName arguments, followed by stack trace elements of the specified exception after the common ancestor.
rewriteCallStack(Throwable
the exception to merge with the current call stack
exception, String
the class name of the common ancestor
className, String
the method name of the common ancestor
methodName)

Rewrite the call stack of the specified exception so that it matches the current call stack up to (included) the specified method invocation.

private static CacheOperationInvoker.ThrowableWrapper rewriteCallStack(Throwable exception, String className, String methodName)

Rewrite the call stack of the specified exception so that it matches the current call stack up to (included) the specified method invocation.

Clone the specified exception. If the exception is not serializable, the original exception is returned. If no common ancestor can be found, returns the original exception.

Used to make sure that a cached exception has a valid invocation context.

Parameters
exception:Throwable

the exception to merge with the current call stack

className:String

the class name of the common ancestor

methodName:String

the method name of the common ancestor

Returns:CacheOperationInvoker.ThrowableWrapper

a clone exception with a rewritten call stack composed of the current call stack up to (included) the common ancestor specified by the className and methodName arguments, followed by stack trace elements of the specified exception after the common ancestor.
