Subject [jira] Commented: (DERBY-3946) Provide support for using the Derby parser to generate Abstract Syntax Trees
Date Fri, 19 Feb 2010 00:24:27 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12835523#action_12835523

Derby Ciu commented on DERBY-3946:

Hi Rick,

         I tried applying the patch derby-3946-01-aa-standaloneParser.java in Eclipse IDE,
which says "The patch has segments that did not match. are you sure you want to apply?" .
 Am I supposed to review a patch w.r.t the local file system and manually merge any unmerged
Also, could you be specific about where should ASTParser.java be placed? I had placed it in
org.apache.derby.impl.sql.conn package and upon running it, I get an ArrayIndexOutofBound
Exception in lines 76, 85 of ASTParser.java
Am I missing out any step while applying this patch?
