Eirik Bakke created NETBEANS-4177:
-------------------------------------
Summary: IOOBE when editing Java file with temporarily missing
comma in method parameter list
Key: NETBEANS-4177
URL: https://issues.apache.org/jira/browse/NETBEANS-4177
Project: NetBeans
Issue Type: Bug
Components: java - Editor
Affects Versions: 11.3
Environment: NetBeans 11.3
Reporter: Eirik Bakke
If, during editing, a comma is momentarily deleted in the parameter list of a
method (in certain cases), an error dialog shows up showing an
IndexOutOfBoundsException in
SemanticHighlighterBase$DetectorVisitor.addParameterInlineHint. A minimized
example exhibiting this behavior is as follows:
{code:java}
public class BugSemanticHighlighterBase {
private Object testMethod(final String arg1 final String arg2) {
return new String("");
}
}
{code}
This example causes the IDE to throw the following exception:

java.lang.IndexOutOfBoundsException: -1
