The MyEclipse 4.0.3 xml editor uses 100%cpu for ever for a large xml document.

I used a document at about 2.4mb.

This is a thread dump.

[Riyad Kalla]

Would you be able to send this file to us for testing and profilign reasons?

[email protected] ATTN Riyad with a link to this post so I know why I”m getting it.

[Panagiotis Korros]

i sent the file as you requested

[Riyad Kalla]

pkorros,
Can you describe in better detail what exactly you are doing and what happens when the XML editor pegs the CPU? I ask because I was editing around in this file and while I agree it is sluggish, I didn’t experience any lockups or anything of that nature.

[Panagiotis Korros]

I agree that editing the file works good.

The problem is that while the file is open eclipse takes all my cpu.

steps to repro…

1. open the file
2. wait for the editor to open
3. open the widnows task manager
4. see that eclipse is responsive (you can edit the file) but the xml editor reconciler takes 100% of your cpu
5. wait for a very long time and notice that the xml editor reconciler still takes 100% of your cpu

[Riyad Kalla]

5) How long did you wait? I’m wondering if the reconciler thread is still running on the file.

[Panagiotis Korros]

I waited for over 15minutes and it was still 100%.

[Riyad Kalla]

The bug has been filed for investigation, thank you
