Steps to reproduce:

Set all of the drop downs in "wrapping" for java formatting to "never."
Create a switch block with case statements containing multiple statements.
Format the section.

Excepted results:

NetBeans fixes other formatting issues (including spaces mismatches, incorrect indentation, etc..) but doesn't break up lines.

Actual results:

NetBeans puts the first statement after the case on the same line, but puts all of the remaining statements (including very short ones like "break;") on a new line.
