Created attachment 130637 [details] IDE log This is hard to reproduce, but I've seen it couple of times. In the attached file, I copied <jsp:useBean.../>, pasted it to line 28 and quickly changed id attribute (as it was already used), suddenly all syntax highlighting after this line 28 stopped working and all below was just plain black (including HTML tags). When I move cursor to some "black" line, it became colored again (but not the jsp:useBean tag, still black). The best way to fix it is to reopen file. It seems that it could happen when I use other than std HTML tags in JSP (jsp, EL...). I'm attaching ide log and sample file.
Created attachment 130638 [details] sample file Product Version: NetBeans IDE 7.3 RC1 (Build 201301240957) Java: 1.7.0_11; Java HotSpot(TM) Client VM 23.6-b04 Runtime: Java(TM) SE Runtime Environment 1.7.0_11-b21 System: Linux version 3.2.0-35-generic-pae running on i386; UTF-8; en_US (nb)
Yes, there's a message in the log: Disabled an invalid highlighting layer: hlStartOffset=769 > hlEndOffset=757 for layer=org.netbeans.modules.editor.lib2.highlighting.SyntaxHighlighting@1183a4a If it's hard to reproduce then it's likely a race condition. There's a message in the log that a write-lock is missing during embedding creation. This problem should be eliminated first. If it does not help then I will search for the problem in the SyntaxHighlighting class itself.

Integrated into 'main-golden', will be available in build *201302010001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/a5f9f2b8175b User: Marek Fukala <mfukala@netbeans.org> Log: #225341 - missing document write lock when creating embeddings on TokenHierarchy
if possible I think it would be good to fix it for patch
Is it still reproducible with the Marek's fix?
yes, still reproducible after Marek's write lock fix Product Version: NetBeans IDE Dev (Build web-main-9941-on-20130220) Java: 1.7.0_15; Java HotSpot(TM) Client VM 23.7-b01 Runtime: Java(TM) SE Runtime Environment 1.7.0_15-b03 System: Linux version 3.2.0-35-generic-pae running on i386; UTF-8; en_US (nb)
The same could happen in certain css files as well: - create new css and paste following: audio:not([controls]) { display: none; } div{ color:red; } - place cursor around on line 5 with "div{" and try to repeat click in source code few times => part of the css becomes black In this case, it is caused by "audio:not([controls])" and I'd say it is 100% reproducible. IDE log contains a lot of INFO [org.netbeans.modules.editor.lib2.highlighting.DirectMergeContainer]: Disabled an invalid highlighting layer: hlStartOffset=11 < previous hlEndOffset=21 for layer=org.netbeans.modules.csl.editor.semantic.GsfSemanticLayer@1a82bf8 Reproducible in 7.3 and latest trunk build Java: 1.7.0_15; Java HotSpot(TM) Client VM 23.7-b01 Runtime: Java(TM) SE Runtime Environment 1.7.0_15-b03 System: Linux version 3.2.0-35-generic-pae running on i386; UTF-8; en_US (nb)
*** Bug 227082 has been marked as a duplicate of this bug. ***
Fixed in GsfHighlightSequence by possibly ending a current highlight (SequenceElement) on next SequenceElement's start offset. http://hg.netbeans.org/jet-main/rev/2df3fc16a103
The CSS issue is fixed, thanks. But JSP issue is still valid, the issue is with SyntaxHighlighting (unlike CSS and Semantic) - please check attached IDE log To reproduce: - paste text of attached JSP file to JSP file in IDE couple of times Product Version: NetBeans IDE Dev (Build jet-main-7697-on-20130313) Java: 1.7.0_17; Java HotSpot(TM) Client VM 23.7-b01 Runtime: Java(TM) SE Runtime Environment 1.7.0_17-b02 System: Linux version 3.2.0-38-generic-pae running on i386; UTF-8; en_US (nb)
I've entered a separate issue 227419 for SyntaxHighlighting reporting invalid offsets and leave this fixed.
