[jira] [Commented] (NETBEANS-4179) Assertion error in javac when saving file with missing comma in method parameter list
[ https://issues.apache.org/jira/browse/NETBEANS-4179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17522079#comment-17522079 ]

------------------------------------------
Not able to reproduce this issue in NB13 with nb-javac. Environment - Windows 10, Runtime JDK- JDK 17
> Assertion error in javac when saving file with missing comma in method parameter list
> -------------------------------------------------------------------------------------
>
> Key: NETBEANS-4179
> URL: https://issues.apache.org/jira/browse/NETBEANS-4179
> Project: NetBeans
> Issue Type: Bug
> Components: java - Source
> Affects Versions: 11.3
> Environment: NetBeans 11.3 with nbjavac plugin installed
> Reporter: Eirik Bakke
> Assignee: Sandeep Mishra
> Priority: Major
> Labels: nbjavac
>
> If, during editing, a method parameter list occurs with a missing comma (in certain cases), an error dialog shows up showing an assertion error in javac every time the Java source file is saved, interrupting the user. A minimized example exhibiting this behavior is as follows:
> {code:java}
> public class BugErrorUncaught {
> private Object testMethod(String param1 final String param2) {
> return null;
> }
> }
> {code}
> This is a variation of the example in NETBEANS-4095, but filed here as a separate bug since the two cause different exceptions at different levels (inside javac here vs. at the semantic highlighting layer in NETBEANS-4095). This example causes the IDE to throw the following exception:

> if (someArg == null) {
> return "foo";
> } else {
> return "bar";
> }
> }
> }
> {code}
> This one produces an error on every single edit.
