]
Eirik Bakke updated NETBEANS-4177:
----------------------------------
Description:
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:
{noformat}
