org.josql.QueryParseException when using a negation
---------------------------------------------------
Key: APLO-122
URL: https://issues.apache.org/jira/browse/APLO-122
Project: ActiveMQ Apollo
Issue Type: Bug
Reporter: Lionel Cons
When trying to use the "NOT" operator in the REST interface, Apollo reports an
exception:
org.josql.QueryParseException: Unable to find function (method):
"NOT(java.lang.Boolean)" in any user-defined function handlers or the default
function handler

FWIW, the expression I tried to use was "(id LIKE '%bar%') AND NOT (id LIKE
'%foo%')".
First, I would have expected such an exception to cause the REST interface to
report a "server error". Instead, it only reported "404 Not Found".
Then, why can't I use the unary NOT this way?
