Thanks for the continued work on this @vudayani ! I must say it's great to see this come in, also taking into account the out-of-bounds-delivered raw feedback. :) I've fixed a minor conflict with imports on main, and added two missing license headers. Let us know if/when you consider this ready for review, or whether there's additional work you still plan to do. |

I think this PR is ready for review and more feedback... Likely , there will be more work to do. |

Thanks for the continued work on this @vudayani ! We're on to a downstream failure right now it seems. `class org.openrewrite.java.tree.J$Erroneous cannot be cast to class org.openrewrite.java.tree.Expression` in `org.openrewrite.java.format.SpacesVisitor`. |

@timtebeek It is ready for review and all tests seem to pass locally. Thanks again for your patience, and sorry for the delay in getting back on this. |

Thanks a lot for all the hard work here @vudayani ! I've tagged Knut for help with review as I'm traveling, and I know Jonathan has been quite busy these past couple of weeks. I hope we can get this in before Wednesday's release, but that'll depend on their feedback as well. |

I'd expected data table rows to be inserted from FindCompileErrors, similar to the example here, but I'm not seeing any reference. Did I overlook something?

What's changed?
The PR introduces handling for erroneous nodes in OpenRewrite. Currently, when there is an error in the LST, the parser may attempt to recover by ignoring or removing the erroneous node to produce a valid LST. The changes in this PR address this by adding a mechanism to handle these erroneous nodes instead of ignoring them, ensuring that they are preserved and correctly processed.
What's your motivation?
The motivation behind this PR is to handle scenarios where errors in the source code could lead to discrepancies in the computed results. When any recipe is executed, the edits are computed on a parsed LST without the error statement. By handling erroneous nodes, we ensure that the error lines are retained and reflected correctly in the LST, leading to more accurate edits and transformations.
Anything in particular you'd like reviewers to focus on?
Anyone you would like to review specifically?
Have you considered any alternatives or workarounds?
Any additional context
This update is crucial for ensuring consistency in scenarios where error lines could affect the outcome of recipes and transformations.
