What steps will reproduce the problem?

1. insert @ getter or @ Setter annotation on a field
2. save the java file

What is the expected output? What do you see instead?

Do you have any save actions enabled? If not, does the edge release fix it? Edge is at: https://projectlombok.org/download-edge.html

the edge version did not solve the problem. I have several save actions enabled. I tried enabling and disabling several save actions to pinpoint the exception and the problems seems to be somewhere in the 'format source code' option. If I disable that it saves without errors.

attached a screenshot of my save actions

That gives us something to go on. Thanks!

This problem is related to the location of the generated methods by the getter and the setter annotation (only for @ Getter and @ Setter directly on fields). They are on exactly the same place as the annotation. The method that throws an error, 'computeMergedMemberDeclarations' uses the locations but doesn't account for this situation. Thus it thinks there must be an inner class as it has eliminated all other possibilities, and this fails. This assumption occurs on org.eclipse.jdt.internal.formatter.CodeFormatterVisitor line 393.

This issue was also present in the 0.9.3 version.
