    Description copied from class: AbstractTraceInterceptor
    Subclasses must override this method to perform any tracing around the supplied MethodInvocation. Subclasses are responsible for ensuring that the MethodInvocation actually executes by calling MethodInvocation.proceed().
    By default, the passed-in Log instance will have log level "trace" enabled. Subclasses do not have to check for this again, unless they overwrite the isInterceptorEnabled method to modify the default behavior, and may delegate to writeToLog for actual messages to be written.
    Specified by:
    invokeUnderTrace in class AbstractTraceInterceptor
    logger - the Log to write trace messages to
    Returns:
    the result of the call to MethodInvocation.proceed()
    Throws:
    Throwable - if the call to MethodInvocation.proceed() encountered any errors
    See Also:
    AbstractTraceInterceptor.isLogEnabled(org.apache.commons.logging.Log), AbstractTraceInterceptor.writeToLog(Log, String), AbstractTraceInterceptor.writeToLog(Log, String, Throwable)
  - getInvocationDescription
```
protected String getInvocationDescription(MethodInvocation invocation)
```
    Return a description for the given method invocation.
    Parameters:
    invocation - the invocation to describe
    Returns:
    the description
