There's an interesting post on stackoverflow concerning the quality of the Eclipse WTP which seems to be decreasing with every major release:
Our company is using eclipse since several years now (we are using WTP since release 0.7)
I am currently evaluating eclipse 3.6.2 with WTP 3.2.3 (...)
WTP 3.2.3 seems to be much slower than 3.0.4.
In fact I am really wondering why WTP gets slower with each release.
We only need basic WTP functionality for developing jsps, xmls and xsd. We don't need high sophistic features like Dali (should JPA tools really covered by a webtools project?), Libra or a visual xml editor in the first place.
The worst thing is that I've got the feeling that the WTP dev team does not care much about performance (e.g. have a look at the http://wiki.eclipse.org/WTP_Performance_Tests page - last update took place in 2008).
But obviously the project has a problem with its quality assurance, especially in terms of performance which affects usability and user acceptance.
[The] team should focus on the things which are essential to most of the users in the first place and afterwards work on implementing super-duper-features.
Does this sound familar to you? I had a déjà-vu while reading this post.
