I'm working through the JFace Data Binding HOWTO at http://www.coconut-palm-software.com/the_visual_editor/?p=57. I've got as far as trying to add the BindSpec, so the code reads dbc.bind(timeWithCompany, new Property(person, "timeWithCompany"), new BindSpec(null, new RegexStringValidator( "^[0-9]*$", "^[0-9]+$", "Please enter a number"))); My code currently reads dbc.bind(timeWithCompany, new Property(person, "timeWithCompany"), new BindSpec(null, new RegE|)); with the cursor after the 'E' in 'RegE'. I type Ctrl+Space to display completions, the window displays (I'll add a screenshot), but I can't choose an option and the following gets displayed in the Error Log when I close the window.

Created attachment 32018 [details] Screen shot of content assist window Added the screen shot.
What build id? This looks like a bug that we fixed already.
It's the 3.2M4 bundle, build ID I20051215-1506.
Then it's not fixed.
Note: if you don't have attached source but a Javadoc location then you might see a small delay. You can reduce the delay on the Java > Editor > Content Assist > Work in Progress preference page (timeout to fetch parameter name). I cannot reproduce this using 3.2 M4 even with invalid Javadoc URLs. Moving to JCore to explain the JME. Can you provide use with your JRE setup (version, is source attached, what's the Javadoc location)?
Thanks for the update Dani. The "small delay" referred to in comment #5 is 20 secs. per entry in the content assist window. I think the problem is the fact that the matched classes are in the sun.misc package, so there's no Javadoc for them. The exact steps I took to cause the problem were: 1. extract a fresh instance of 3.2M4 downloaded from eclipse.org. Run eclipse with the Sun JDK1.4.2_08 configured as JAVA_HOME. 2. create a new workspace. 3. create a plug-in project as specified in the link at comment #0. 4. about two-thirds of the way through the howto, you need to change the last BindSpec line. This is where the problem arose. I didn't change the Installed JRE configuration from the default. The src.zip is present in the JDK directory, no Javadoc is installed on my PC, the Javadoc URL is http://java.sun.com/j2se/1.4.2/docs/api/.
>The "small delay" referred to in comment #5 is 20 secs. Can you provide a stack dump while waiting (in the console hit Ctrl+Break on Windows and kill -3 or kill -QUIT on Linux)?

*** Bug 122113 has been marked as a duplicate of this bug. ***
I could not reproduce the JME in the error log on Windows XP. This looks really close to bug 120559, but the line numbers don't match. And this is supposed to be fixed in M4. Is it reproducable for you?
Sorry for the delay in responding. Do you mean "is the JME reproducible" or "is the 'hang' reproducible"? I can reproduce the 'hang' (i.e. 60 sec pause) everytime. I don't know about the JME, and I won't be able to check now until Monday at the earliest.

I'd like reproducable steps. I followed the steps in comment 0 and it could not get either a hang or a JME. What kind of connection do you have?
