(Consistió en una Charla Corta)  We study numerically the specific heat of a model supercooled liquid  confined in a spherical cavity with amorphous boundary conditions,  which allows us to perform a \acf{FSS} study.  The specific heat of  the metaequilibrium liquid shows a size-dependent peak as a function  of temperature.  We attempt to collapse the data onto a \ac{FSS}  curve according to different theoretical scenarii, obtaining  reasonable results in two cases: a ``not-so-simple'' liquid with  nonstandard values of the exponents $\alpha$ and $\nu$, and  \acf{RFOT}, with two different length scales.  Both scenarios imply  a nonzero critical temperature.  The conclusion is compatible with  data obtained for periodic and random boundary conditions.
