[eclipse-dev] Eclipse creating hprof file in project root

[Shawn Heisey <eclipse@xxxxxxxxxxxx>]

I tried to find an eclipse users list, but came up empty. I am already 
subscribed to this list. I know this is probably off topic.

I have eclipse 2022-12 (4.26.0) running on Ubuntu server 22.04 with
OpenJDK 17. I use X11 forwarding over ssh to have it display on an 
Ubuntu Desktop 22.04 machine.

I cloned the Apache Solr repo, changed branches, ran the gradle target
to build the eclipse project, and imported it into eclipse.

Today I noticed that it was saying the git repo had changed when I 
haven't modified anything. A git status revealed the change:

---
elyograg@smeagol:~/git/solr$ git status
On branch branch_9x
Your branch is up to date with 'origin/branch_9x'.

Untracked files:
(use "git add <file>..." to include in what will be committed)
java_pid2644211.hprof

nothing added to commit but untracked files present (use "git add" to track)

A look at ps revealed what is running at that PID:

---

I have not touched java.io.tmpdir, so I would have expected that file to
be created in /tmp instead of the project root. I don't know why eclipse 
seems to think that Solr is a spring boot project ... it isn't.

The process that created the hprof file is quite obviously related to
Spring. Is there anything that I can learn here, or will I need to ask
the Spring project? I have Spring Tools Suite 4.17.2.RELEASE installed 
from Eclipse Marketplace.

Thanks,
Shawn
