#### Problem Description
Eclipse launches, terminal window is functional and About details may be displayed. However File > Open raises an Unhandled event loop exception and wants to exit. 2020-06 newly installed into /tmp for testing. An existing version of Eclipse 3.8 exits on mounted removable media.

#### Platform and Environment
+ Eclipse Binary: www.eclipse.org/downloads distribution
+ OS: HP ThinPro 7.1.0 Build 18 (Latest), OEM'd Linux Ubuntu 16.04LTS x86_64
+ Java: OpenJDK 1.8.0.242-8u242-b08-0ubuntu3~16.04-b08
+ HW: HP ThinClient. Packages not allowed to be installed to root flash (invalidate support) so are USB sticks. Eclipse 2020-06 in /tmp for testing before, prospectively, being reinstalled (using the installer) to mount point outside of OS root. HP ThinPro 7.1.0 is distributed with Firefox 68.9.0

#### Attempted Resolution
1. Consulted the FAQ section "Know Issues", "General Problems: General Startup"
2. Tried alternative JREs: Oracle jdk1.8.0_202 and Oracle jdk-11.0.2 tried with same result
3. Tried adding Firefox location to `MOZILLA_FIVE_HOME` and prepending that to `LD_LIBRARY_PATH` (see panel)
5. Tried defining `swt.browser.DefaultType` in eclipse.ini as follows `org.eclipse.swt.browser.DefaultType="mozilla,webkit"`
4. Consulted the Beginners Forum

ECLIPSE_HOME=/tmp/jee-2020-06/eclipse \
MOZILLA_FIVE_HOME=/opt/firefox \
LD_LIBRARY_PATH=${MOZILLA_FIVE_HOME}:${LD_LIBRARY_PATH} \
/tmp/jee-2020-06/eclipse/eclipse

Eclipse launches but with warnings:

** (eclipse:16505): WARNING **: Couldn't connect to accessibility bus: Empty address ''

** (java:16532): WARNING **: Couldn't connect to accessibility bus: Empty address ''
org.eclipse.m2e.logback.configuration: The org.eclipse.m2e.logback.configuration bundle was activated before the state location was initialized.  Will retry after the state location is initialized.

Do you have an error log you can post? It would be hidden in your workspace directory as the .metadata/.log file.

Nitin, many thanks for a prompt reply.

I'm totally new to Eclipse and had never used 3.8, so please bear with me -- even the concept of what a workspace or the workspace is, isn't yet fully understood.

$ find ~ -name '*metadata*.log' -ls 2> /dev/null
$ find ~ -name '*workspace*.log' -ls 2> /dev/null
$ find ~ -name '*eclipse*.log' -ls 2> /dev/null
    42234      0 drwxr-xr-x   1 michael  telco          38 Jun 22 08:08 /home/michael/eclipse-workspace/.metadata/.plugins/org.eclipse.ui.views.log
$ ls -l /home/michael/eclipse-workspace/.metadata/.plugins/org.eclipse.ui.views.log
total 4
-rw-r--r-- 1 michael telco 729 Jun 22 22:27 dialog_settings.xml

Unless I'm doing it wrong, there aren't any log files under the workspace (it suggested to create in my home directory (rather than /tmp) and I accepted so they should be there, not in /tmp), but I've checked:

$ cd /tmp
$ find . -name '*metadata*.log' -ls 2> /dev/null
$ find . -name '*workspace*.log' -ls 2> /dev/null
$ find . -name '*eclipse*.log' -ls 2> /dev/null

Exporting to a file from the Eclipse workspace of course throws the same error, so I've used the copy to clipboard and put-up a couple of the red fatal "Unhandled event loop exception"s here:
* https://pastebin.com/t5PP696z

Again, thank you for your help -- it's much appreciated.

The log file's name is simply ".log".

I think you need a newer GTK version. https://www.eclipse.org/swt/faq.php#gtkstartup details the version requirements.

Hi Nitin, gtk3.18.9 is part of the HP ThinPro 7.1.0 Build 18 Service Pack 8 (release notes: ftp://ftp.hp.com/pub/tcdebian/updates/7.1.0/service_packs/ThinPro7.1_SP-8.5.txt).

Anything that's installed in the package database is delivered by HP in their OEM'd version of Ubuntu 16.04LTS. 16.04LTS is in mid term maintenance (https://ubuntu.com/blog/what-is-an-ubuntu-lts-release). I am not aware of HP's plans to rebase on a later release. I cannot recall any wanted package not available because of use too old a release of the OS so would be surprised if the conclusion of this is that Eclipse simply isn't available to HP's entire thin client base.

Kind regards

Quote:

| Q: Which GTK version do I need to run SWT?
| * Eclipse/SWT 3.8.x: GTK+ 2.6.0 and its dependencies

Per the subject-line, GTK+ 3.18.9 is newer than 2.6.0, so, unless I've misread or misunderstood the FAQ topic cited, I don't understand why I need a newer version.

Apart from that, the version of GTK+, GTK+ 3.18.9, is not something I have any control over. If Zoom (with its bidirectional AV) and many apps couldn't run on HP ThinPro, then I'd willingly accept that I was being unrealistic in expecting a modern app to run on such an antique. But that isn't the case.

HP ThinPro 7.1.0 Build 18 Service Pack 8 is the latest (last updated a couple of months ago). Whilst one might wish for HP to update to a later base than Ubuntu 16.04LTS, if they thought it was preventing Customers from running contemporary apps, I'd imagine that they'd have re-based it. I'm surprised and disappointed that Eclipse is unusual in not being able to run on HP ThinPro 7.1.0/Ubuntu 16.04.

2020-06 is Eclipse/SWT 4.16. That means GTK 3.20 is what's expected, and the 4.16 plan details Ubuntu 20 LTS as a target O.S.

"org.eclipse.swt.SWTError: No more handles" is not something you usually see on on startup, so the fact that your installed version of GTK is below the expected minimum is the first thing that stood out as a possible problem--that, and your Java Runtime's "vendor" property is reported as "Private Build". Either way, this sounds like something to ask HP support about. There's no way to tell if something they've done to make their thin client OS work or be secure is somehow involved and actually the cause.

Please see point No. 2. Under attempted resolution in the OP that addressed the matter of JRE version.

I can confirm that I had the same issue after upgrading to Eclipse 2020-09 on Ubuntu 16.04. My GTK version was 3.18 but upgraded with these instructions:

sudo add-apt-repository ppa:gnome3-team/gnome3-staging
sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt update
sudo apt dist-upgrade

After upgrading I am able to browse files in Eclipse. Hope this helps.
