Latest eclipse 2020-03 was working perfectly on 1.3 Funtoo.

After upgrade to 1.4 same eclipse started crashing with below:

(Eclipse:20895): Gdk-CRITICAL **: 19:51:53.798: ../gtk+-3.24.17/gdk/wayland/gdkdisplay-wayland.c:1328: mmap'ping shared memory file failed: Invalid argument

2. A fatal error has been detected by the Java Runtime Environment:
4.  SIGSEGV (0xb) at pc=0x00007f9d17c2d345, pid=20895, tid=0x00007f9dcc3b7700
6. JRE version: Java(TM) SE Runtime Environment (8.0_202-b08) (build 1.8.0_202-b08)
7. Java VM: Java HotSpot(TM) 64-Bit Server VM (25.202-b08 mixed mode linux-amd64 compressed oops)
8. Problematic frame:
9. C  [libwayland-client.so.0+0x6345]  wl_proxy_marshal_constructor+0x85

Not sure however if this is not eclipse problem.
The only reason why I am reporting it to Funtoo community is because it was working before upgrade.

If anybody can provide quick instruction on how to test eclipse with other version of GTK+ v3, I am happy to do the test.
However I am not familiar with ebuilds and I don't want to build it manually from sources as I don't want to mess up my system with custom files.
