Bug 543727 - False positive "Unnecessary cast"

- change EqualExpression.resolveType() to add additional check
  before reporting an unnecessary cast if one side is parameterized
  and the other is a cast of a base type that may be compatible
  with parameterized type when boxed
- add test to CastTest

JDT Core

This is the core part of Eclipse's Java development tools. It contains the non-UI support for compiling and working with Java code, including the following:

  • an incremental or batch Java compiler that can run standalone or as part of the Eclipse IDE
  • Java source and class file indexer and search infrastructure
  • a Java source code formatter
  • APIs for code assist, access to the AST and structured manipulation of Java source.

For more information and important links, refer to the [JDT wiki page] 1 or the [JDT project overview page] 2.
