[manticore-projects]

Greetings! thank you for your contribution. Changes are needed though:

1. please resolve the choice conflict in the grammar

 Warning: Choice conflict in [...] construct at line 1682, column 78.
         Expansion nested within construct and expansion following construct
         have common prefixes, one of which is: "TABLE"
         Consider using a lookahead of 2 or more for nested expansion.

2. please update the keywords after as explained here: https://manticore-projects.com/JSQLParser/contribution.html#manage-reserved-keywords

Much better already, but Q/A still fails. Run './gradlew :spotlessApply' to fix these violations.
In general, run './gradlew :check' before pushing.
