full stacktrace

I am upgrading this to a P1 because I have Reproduced with Plain Web project -
on both Windows and Solaris using jdk1.5.0_12 with Beta1 09061200. I have not
been able to reproduce with jdk1.6.

There are a couple of paths to reproducing: make edits, then press toolbar save all, then contextmenu on web project to
close *or* edit, then press File->Close on the project. Two or three cycles of either method then File>Reopen project 
will reproduce the error. Thereafter no more data can be saved to the project.

There in nothing from editor in the stacktrace, it probably openide or project bug. Reassigning

the problem is with the web/Page1.jsp file.
probably something in 
org.netbeans.modules.visualweb.project.jsfloader.JsfJspEditorSupport or
org.netbeans.modules.visualweb.project.jsfloader.CompoundSaveCookie.save()

reassigning to visualweb

FS part says, that writing to *.jsp file isn't save to do because reading from it is still in progress (even after
2000ms delay) - thus exception is thrown. In other words FS tries to ensure reading/writing exclusivity.

Milos is probably right, visualweb.

Additional info:

As mentioned by Krystina the exception occurs for a non-visual web project also. Open project, modify welcomeJSF.jsp ans
save, close project. After second or third try the exception occurs.

Attaching the message log for my run.

Message log for non-visualweb project case.

The designer doesn't manage the files. Why is it assigned here?

OK, Sandip provided it is reproducible for non-visual projects as well, passing there.

If it helps debugging...I set a breakpoint inside on FileInputStrem CTOR and dumped the stacks. Here are a few stack
traces just prior to the exception in a non-visualweb JSF page. In the last exception notice the call to :

org.netbeans.modules.localhistory.utils.FileUtils.copy() method from within the 
org.openide.text.DataEditorSupport$Env.outputStream() call which is saving the document.

Try to reproduce with LocalHistory module turned off.

Please ignore the last comment about 

org.netbeans.modules.localhistory

module. Disabling the module did not help :(

Marek, could you look at this? Probably the jsp file has an open stream for reading. 

I have added some debugging code to the MutualExclusionSupport so I am able to find who is the one who gets the stream
but doesn't close it. As is shown below the problematic code is JavaSourceObject in particullar its JSP implementation
from org.netbeans.modules.web.core.syntax.JavaSourceProviderImpl.

The implementation of the forFileObject() returns FilterImpl() with following implementation:

  public Reader filterReader(Reader r) {
      return new StringReader("class SimplifiedJSPServlet {}"); //NOI18N
  }

This code not wrapping the given reader causes that the reader _r_ is never closed and hence the MutualExclusionSupport
still holds the info about the file stream being read. 

Since the implementation of MutualExclusionSupport holds the info about the resource being used just weakly there is a
workaround: after facing the described problem, cancel the saveAll dialog, invoke GC in the ide and then save the documents.
    
I am not sure if this is a P1 since there is a workaround, but OTOH not so much straightforward. In any case reassigning
to Jan Lahoda which is the author of the code.

ALL [null]: Cannot get exclusive access to /marek/NetBeansProjects/WebApplication4/web/index_1.jsp (probably opened for
reading).
ALL [null]: There were some problems while saving index_1.jsp.

Fixed in trunk. Workarounded on the web side, thought the proper fix should be done in the infrastrucure. Honzo, please
remove this once you fix this issue properly. I am downgrading to P2 and kindly asking QE to test it and Honza Lahoda
and Petr Pisl to check the change so I can fix to beta1 branch.

+    try {
+        r.close();

+       Logger.global.log(Level.WARNING, "Cannot close stream.", ioe);

    return new StringReader("class SimplifiedJSPServlet {}"); //NOI18N
}

I agree with the proposed solution. 

The workaround is OK IMO. Thanks.

Marku, QE approved fix in beta1 branch. Please, commit fix today. Thanks

fixed in release60_beta1 branch.

Honzo, can you do the proper fix in trunk please? Thanks.

The API is friend anyway, so P3 should be enough, IMO.

moving opened issues from TM <= 6.1 to TM=Dev

Reopen if you disagree.

I still keep getting this error in 6.9.1!

Could you pls repopen and fix it.

Thanx

Could I ask you please to file a new issue and attach a new stack trace. Current one is from 2007. Thx.
