[jira] [Updated] (CALCITE-1360) Custom schema in file in current
directory gives NullPointerException
[ https://issues.apache.org/jira/browse/CALCITE-1360?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Julian Hyde updated CALCITE-1360:
---------------------------------
Description:
ModelHandler won't accept a file name without a directory component. A model referencing file with no directory component throws an NPE. In the example below replacing {code}foo.json{code} with {code}./foo.json{code} resolves the problem.
