Eclipse conditional breakpoint compilation error "==" invalid AssignmentOperator

Question

So if I got it right, you're supposed to use a boolean expression for the condition. Yet when I try to use impact == null I get the following error:

Conditional breakpoint has compilation error(s).

Reason:
Syntax error on token "==", invalid AssignmentOperator.

What gives? What did I do wrong, and how do I fix it?

Answer 1

Just a wild guess as I faced a similar problem some moments ago: You have written impact == null; instead of impact == null.

If this is the case: try removing the semicolon.
