Eirik Bakke created NETBEANS-4179:
-------------------------------------
Summary: 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
If, during editing, a method parameter list occurs with a missing comma (in
certainc 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:
