Build Identifier: 3.7 After some time of working with Eclipse (~ a day or two) I see empty shells. Looks like the no more handles situation on windows computers. I suspect that random crashes of Eclipse are related to this, but I can't confirm, but I have learned to restart Eclipse quickly once I see the empty shell of approaching death. Reproducible: Sometimes Steps to Reproduce: 1. Work With Eclipse 2. 3.

what version of mac os x are you running ? is that git support that you have installed, anything else ?
I see that since I upgraded to Lion (10.7.1). Not git, but Jazz/RTC installed.
Just ran into this working with SWT Paperclips - print preview appearing as a blank white rectangle with Lion, worked fine with Snow Leopard. I've been doing some digging and at least in my case it appears the problem is caused by creating a GC with a Printer device. The GC doesn't need to be used, just created. Here's a snippet that causes the problem on my OS X Lion install: public class DialogTest { public static void main(String[] args) { /* Take this line out and it works */ new GC(new Printer(Printer.getDefaultPrinterData())); Display display = new Display(); Shell shell = new Shell(display); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } }

bug 359316 has crash logs that happen after seeing this bug. I've seen it with both 10.6 and 10.7
Silenio, there is a snippet in comment 5, could you please try that on your Lion ? Thanks Lakshmi, do you have Lion installed already ?
The problem from comment#5 happens on Lion and Snow Leopard for me. It happens because the sample code is not calling printer.startDoc()/printer.endDoc(), which could be considered an application error. I will attach a patch that solves this problem, but the patch will not be released for now. It requires more testing and I believe this problem is not related to original problem or to the problem in comment#6. Those are probably memory leaks (shells not being disposed properly?). It could be a bug in the application code or in SWT. Johannes, Adam, do you have any other plugins install (which are not in the Eclipse SDK)?

I have the following: Emma EGit TeamCity Google Suite I also got another crash on saving with a log and exception, I can post that if it would help at all.
Btw, I saw this problem before TC plugin, but I don't remember for the others.
I run the following snippet on Snow Leopard (the snippet leaks shells). I am able to create 704 shells before I get a blank shell. If I uncomment the line that disposes shells the snippet finishes properly. import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; public class Test356601 { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); shell.setLayout(new GridLayout(1, false)); for (int i = 0; i < 1000; i++) { System.err.println(i); Shell s = new Shell(); s.setVisible(true); // s.dispose(); } shell.pack(); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } }
Created attachment 207439 [details] CrashReport from crash after seeing black shells. I saw three blank shells for dialogs and then eclipse crashed.
Created attachment 208033 [details] BadLocationException I get lots of BadLocationException exceptions in the workspace log before I see the blank dialogs. See attachment.
I am assuming this is happening because of this shell leak. *** This bug has been marked as a duplicate of bug 338975 ***
