If a file does not have an associated project in the workspace the analysis fails. This is the case when dragging a file onto Eclipse from outside of the workspace. The stack is:

Internal error evaluating editor-analyze (InterpreterException; see error log)
rewriting failed, trace:
editor_analyze_0_0
editor_analyze_0_0
analysis_single_default_interface_0_0
analysis_single_default_3_1
analysis_message_update_partitions_queue_0_2


Neither syntactic nor semantic errors are reported. No analysis failed messages is given either (might be good).

While it may be hard to provide meaningful semantic errors without a project for a language with imports or cross-file references, syntactic errors can always be presented.

This appears to be an unhandled case in the JDT as well.
