Description Brett Kotch

Type 

ArrayEnumeration e

and assume that ArrayEnumeration isn't imported yet. The quick fix notifying to 
import ArrayEnumeration doesn't show up till after I type the entire line! 

ArrayEnumeration e = null;

Right after I type "null;", seeing no errors I hit return. But then the quick 
fix pops up. Since I am on a different line, I can't use ctrl-1 to quickly pop 
the fix up ... but I have to go to the previous line, or drag my mouse over to 
the fix. 

To make matters worse, if I start typing on that second line ... i.e. 

ArrayEnumeration e = null;
String s

The quick fix doesn't even appear. I can go on typing like this for some time. 
Not until after I am finished typing the second, will that quick fix appear, 
but only if I wait long enough. If I start the third line ... no quick fix.

This has to do with the error tollerance of the AST. A missing semicolon is
(unfortunatly) already enough to prevent the creation of other statements.

In the given examples I think for 'ArrayEnumeration e' it is clear that there
won't be an AST.
But for 
ArrayEnumeration e = null;
String s
I think the first statement should appear.

Moving to jdt.core.

We don't have error recovery at the statement level. A syntax error will prevent
the AST from being created, because the rule cannot be reduced in the parser.
