Julian Hyde commented on CALCITE-1993:
--------------------------------------
I suspect that {{getSubSchema("PUBLIC")}} is returning null. I wonder whether
h2 has public synonyms, and the adapter is getting confused and thinking that
there is a schema called "PUBLIC".
> Possible bug - NPE when using H2
