How to get eclipse code formatter to wrap assignment statements onwards = operator

Question

I'm using eclipse code formatter, and I've set maximum line length to 120. If an assignment statement is longer than 120 characters, for example

private Map<Instruction, LocalRegisterAssignmentInformation> instructionRegisterMap = new IdentityHashMap<Instruction, LocalRegisterAssignmentInformation>();

I would like the formatter to wrap this line and make the statement look like this:

private Map<Instruction, LocalRegisterAssignmentInformation> instructionRegisterMap
  = new IdentityHashMap<Instruction, LocalRegisterAssignmentInformation>();

But the formatter doesn't seem to wrap it. I tried finding relevant options in the eclipse formatter profile settings, but couldn't find any.

Edit your Java formatter profile as follows:

1. In Line Wrapping select Expressions > Assignments
2. Set Line wrapping policy to Wrap where necessary
3. Check the checkbox Wrap before operator
