-------------------------------------------
See reasoning and workaround in NETBEANS-6349
> trying to indent throws java.lang.NoSuchMethodError exception
> -------------------------------------------------------------
>
> Key: NETBEANS-6286
> URL: https://issues.apache.org/jira/browse/NETBEANS-6286
> Project: NetBeans
> Issue Type: Bug
> Components: editor - Formatting & Indentation
> Affects Versions: 12.6
> Reporter: Jason Mayeaux
> Priority: Major
> Labels: Indentation, editor
> Attachments: messages-2.log
>
>
> I opened an existing project and hit Enter to start a new line, which threw
> an error. Unexpectedly the new line did not have the indentation level of the
> previous line.
> I hit Tab to indent the line, and the line did not indent, instead throwing
> the error again.
> I went to Tools > Options > Editor > Formatting to check my Tabs and Indents
> settings, which threw the error again as I opened the Formatting tab.
> I tried again in other class files and even making a new project. I closed
> and reopened the project, and closed and reopened NetBeans. Attempting to
> indent lines seems to never work and always throw this error. I am only able
> to indent lines of code by manually hitting the spacebar, copypasting space
> characters, or using the Source > Format menu option.
> I have even tried deleting my "userdir" at %appdata%\NetBeans\12.6 which did
> not fix the issue.
> Needless to say, creating and indenting new lines of code is something a
> developer must do often, so I consider this a nontrivial issue and it
> significantly slows my workflow.
> A message in the IDE each time encouraged me to report this issue here, so
> here I am. I hope I have submitted this issue correctly, but I am new to
> JIRA, so please forgive mistakes.
