[jbosstools-issues] [JBoss JIRA] (JBIDE-12405) As-you-type validation works slow when many strings are being added

[Alexey Kazakov (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-12405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12710815#comment-12710815 ] 

Alexey Kazakov commented on JBIDE-12405:
----------------------------------------

1. Create the following class: 

{code}
package test;

import javax.enterprise.inject.Produces;
import javax.inject.Named;

public class Bean_Broken {

	public void foo() {
		String s = "#{string.ss}";
		String s2 = "#{string.ss}";
	}

	@Named
	@Produces
	public String string() {
		return "";
	}
}
{code}

3. Both ELs are marked as a problem
4. Copy String s2 = "#{string.ss}";
5. Delete it.
6. Past String s2 = "#{string.ss}";
7. There is no validation problem on the second EL.
8. Add " " to the second string: String s2 = "#{string.ss} ";
9. The EL has a problem annotation now.

> 1. Create a cdi bean class.
> 2. Add the following lines to any method of the class:
> {code}
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> 			System.out.println("#{test.bytess} sf sdf " + "" + "" + "");
> {code}
> 3. Repeat #2 a ten times.
> 4. There are 0.5n(n+1) as-you-type validation thread created, where n is a nubmer of srings of the file.
> So if you copied a hundred strings you will have 5050 threads.
