Knut Anders Hatlen commented on DERBY-2785:
-------------------------------------------
I see you've already solved the NPE in ij, but I thought I'd mention the
ij.exceptionTrace property in case you need to debug similar problems later.
The property makes ij print the stack trace when it encounters an exception:

> ij "describe" built in command cannot describe a table named "run"

> Key: DERBY-2785
> URL: https://issues.apache.org/jira/browse/DERBY-2785
> Project: Derby
> Issue Type: Bug
> Components: Tools
> Affects Versions: 10.2.2.0
> Environment: OS-X, Java 1.5
> Reporter: Tim Halloran
> Assignee: Eranda Sooriyabandara
> Priority: Minor
> Attachments: caidentifier.diff, caidentifier.diff, derby-2785.diff,
> derby-2785.diff, derby-2785.diff, derby.log, derbyall_report.txt,
> derbyall_report.txt, describeKeywords.diff, junitAll.out, junitAll.out, step
> logs.txt, test.out

>
> steps to duplicate:
> (attach ij to any database)
> ij> create table run (i int);
> 0 rows inserted/updated/deleted
> ij> desc run;
> ERROR 42X01: Syntax error: Encountered "desc" at line 1, column 1.
> ij>
> I think this is a parser problem within ij where the "run" is taken as a
> token and that token is not included in the definition of a tablename
> expression in the grammer (should be an easy fix).
