Missing suggestions for static methods in code assist when parser recovery involved

[mauromol]

Consider the following:

package test24
import java.text.NumberFormat
class Test24 {
	static main(args) {
			NumberFormat.|
			Set<Integer> s = []
	}
}

Invoke code assist at "|" with Ctrl+Space and start typing getN: getNumberInstance is not shown as a suggestion. Press Esc and Ctrl+Space again: voilà!
If you remove the following line (Set<Integer> s = []), code assist works fine from the beginning.

Because of optional semicolons in Groovy, you are completing on the expression NumberFormat.|Set<Integer> ... which parses much differently than NumberFormat.| followed by semicolon or } or a keyword like if. If you want to insert in the middle of a section of code, starting with a semicolon and then adding any partial stuff should give you completion similar to end of block editing.

Tested with 3.1.0.xx-201808212342-e47, but it does not work as expected. In the exact case I attached here, when invoking Ctrl+Space at NumberFormat.|, I just get NumberFormat.Field completion. If I invoke it at NumberFormat.getN| it works though.
However, if you hit Ctrl+Space with NumberFormat.|; (note the trailing semicolon), it works as expected.

Okay, yes. I was testing without the generics on the Set declaration. Without that, the proposals come normally.

[eric-milles]

Ready to test. Recovery is very specific to this case; you may find other cases where it breaks down.

Works well in 3.1.0.xx-201808221857-e47, thank you! 👍
