Known issues on Eclipse 4.2

There are several problems on Eclipse 4.2. If you want to avoid them, use Eclipse 3.8(latest version of 3.x stream, not older than 4.2) instead of 4.2.

Massive performance problem

Bug 384916 - Switching between tabs is very slow (note that zend does not fix this bug)
Bug 359059 - [Commands] [Compatibility] Undefined context error when restarting with a PHP file open

Workaround on 4.2: (choose 1 or 2)

1. Install "Eclipse Web Developer Tools".
2. Start eclipse with any perspective except PHP. (e.g. Resource perspective)
