Description Alexey

Build Identifier: 20100617-1415

I receive complain about this line of code:
List<String> emails = new ArrayList<String>();

Description	Resource	Path	Location	Type
The type Collection is not generic; it cannot be parameterized with arguments <? extends E>	B.java	projectname/notifications	line 29	Java Problem

If I comment this code, there are a lot of weireg problems, for example imports dont work

Reproducible: Sometimes

Steps to Reproduce:
Bug is difficult to reproduce. I checkout whole project, set up environment (dynamic web project, tomcat) and get such error. When I copy .metadata & .settings dir from another workspace (another svn branch) and switch it to my branch it is ok. But sometimes this happens again and I need to overwrite metadata & settings folders.

I use 1.6.0_20 java & Tomcat 5.5. In compiler settings I use 1.6 (default values) for all settings.

What is the version of the JRE you are using, Anything below 1.5 will
trigger this problem. This is surely a set up issue.

I'm using 1.6
The problem was with cryptix library. I removed it from classpath, and problem disappeared. Probably it is not an Eclipse issue, but the problem is weird and probably it is usefull. Thanks.
