Description _ potingwu 2004-05-28 00:04:49 UTC 
Often got the following exception:

javax.swing.text.BadLocationException:
reqPos=2634, reqLen=-2379, doc.getLength()=2643

org.netbeans.editor.LineRootElement.prepareSyntax(LineRootElement.java:203)

org.netbeans.editor.fold.spi.FoldHierarchySpi$1.propertyChange(FoldHierarchySpi.java:719)
       ...


In NbJavaFoldMaintainer.java,
Ln#383:            int startOffset =
elem.getStartOffset();
Ln#384:            int endOffset =
elem.getEndOffset();

startOffset = reqPos = 2634
endOffset = 255

that caused reqLen = -2379.

I guess "2634" is for the full doc, and "255" is
for the collapsed doc. Is it some kind of sync.
problem (race condition)

And sometimes we also got the following
exceptions, maybe from the same reason:

java.lang.IndexOutOfBoundsException: Invalid line
index=92 >= lineCount=92

The first part of the problem should be fixed by the fix of issue
42504 (already backported into custom_folds).
Could you please provide a full stacktrace of the second problem? I
would like to know from where the
org.openide.text.DocumentLine$Set.getCurrent(DocumentLine.java:904)
gets called because the DocumentLine.Set.getCurrent() is declared to
throw the exception in case the given line is invalid so the caller
should be aware of that. Thanks.
