Eclipse Unhandled event loop exception no more handles - Windows 7 64 bit
I have tried searching but cannot find my answer. I would appreciate any help.
I get this error when editing 2+ windows in Eclipse.Version: Luna Service Release 1 (4.4.1). eg., Open 2 class windows.
When clicking one panel to make class A active. If I click Class B to make Class A the active panel I get the same error.
Workaround is to close so I only have one panel showing for editing my class.
Unhandled event loop exception

I also get:
Warning: The environment variable HOME is not set. The following directory will be used to store the Git
user global configuration and to define the default location to store repositories: 'C:\Users\Chris'. If this is
not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
EGit might behave differently since they see different configuration options.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.
But I have tried to install Git within Eclipse to no avail.
Thank you in advance, Chris

In most cases, the reason is having some resources (controls, images, fonts...) not disposed.
But e.g. for creating controls, exception is being thrown, when OS.CreateWindowEx() returns 0 (you can refer to https://msdn.microsoft.com/ru-ru/library/windows/desktop/ms632680(v=vs.85).aspx for more details)
(This relates to Windows impl of SWT only of course)
- You can use free Sysinternal Process Explorer to check whether you've actually taken too much handles (In Process Explorer wnd, choose View>Select Columns... > Process Memory tab > check "USER Objects")
- Possible reason can be e.g. passing invalid parent into control's constructor
Hope this helps

I had the same problem on Fedora 25 / Eclipse Neon.3. After lot of searching I found this Eclipse bug. Workaround for any Fedora/Linux users if they find same issue is to run following commands before starting Eclipse:
export SWT_WEBKIT2=1
export SWT_GTK3=0
./eclipse

For me it was fixed by turning off "nVidia Desktop Manager".
Other people fixed the problem by turning off other desktop manager apps like "DisplayFussion".
