When trying to edit a function name or default value using table editor, the field editor gets off the table (is moved into a new separated window) and doesn't allow editing. When that separated window is closed, the JVM gets terminated with "Exit code=1". Steps to reproduce: 1. Create a simple JS with a function with an argument, like: function test(name) {} 2. Right-click on the function name and select Refactor->Change Function Signature 3. Click on 'name' in the parameters table. FAIL: Looks like nothings happen for the first time. 4. Click on 'name' in the parameters table again. FAIL: The field editor gets opened in a new window. Clicking on the Wizard's dialog window closes that new window, but if you click on 'x' button in fields separated window's titlebar JVM get's terminated with "Exit code=1" and the following message appeared in error output: Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged. 5. The following start of Eclipse fails with the following error output: [eclipse]$ java.lang.RuntimeException: Error initializing storage. at org.eclipse.osgi.internal.framework.EquinoxContainer.<init>(EquinoxContainer.java:77) at org.eclipse.osgi.launch.Equinox.<init>(Equinox.java:31) at org.eclipse.core.runtime.adaptor.EclipseStarter.startup(EclipseStarter.java:295) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:231) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:648) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:603) at org.eclipse.equinox.launcher.Main.run(Main.java:1465) at org.eclipse.equinox.launcher.Main.main(Main.java:1438) Caused by: java.io.EOFException at java.io.DataInputStream.readInt(DataInputStream.java:392) at org.eclipse.osgi.container.ModuleDatabase$Persistence.readWire(ModuleDatabase.java:1168) at org.eclipse.osgi.container.ModuleDatabase$Persistence.load(ModuleDatabase.java:1028) at org.eclipse.osgi.container.ModuleDatabase.load(ModuleDatabase.java:879) at org.eclipse.osgi.storage.Storage.<init>(Storage.java:145) at org.eclipse.osgi.storage.Storage.createStorage(Storage.java:85) at org.eclipse.osgi.internal.framework.EquinoxContainer.<init>(EquinoxContainer.java:75) ... 11 more Gtk-Message: GtkDialog mapped without a transient parent.

The field editor gets detached from the table as a result of set of subsequent calls to layout() method during the editor activation. layout() method calls org.eclipse.swt.widgets.Table.getClientArea() which, in its turn, calls OS.gdk_window_get_origin (binWindow, binX, binY); (at line 1157). One of these subsequent calls detaches the editor into a separated window.
Very similar effect happens with JDT's Refactor->Change Method Signature Wizard. There is also field editor isn't working: some 'new' window appears upon the field editor's activation (but it quickly get's closed or hidden) and the editor isn't activated as the result (so you cannot use it to edit a method name).
On Luna it works well. The issue appears only on Mars.

It looks like cleaning the configuration ('./eclipse -clean') helps to start eclipse, if its configuration was broken in the way described in #5 of description. The configuration corruption itself looks like an accidental thing - it cannot be reproduced every time when JVM is crashed, but happens from time to time.
