Description

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.

Here is a stack trace:
