IntelliJ IDEA 14.1 slow to launch Tomcat 7 EE web application

Question

Mac OSX 10.9.5 / Tomcat 7.0.62/ java version "1.8.0_45"/ IDEA 14.1.3

I'm experiencing some odd behavior getting IDEA to launch an exploded war to Tomcat as a local Tomcat server configuration.

By itself, Tomcat starts immediately if I run its scripts (i.e., startup.sh or catalina.sh start | run) and the webapp is accessible from a browser. Command line apps run immediately in IDEA. The problem is just when I run a web application from inside IDEA, trying to deploy the exploded app to Tomcat local. Changing the browser in the configuration has no effect.

When I hit "run" there's nothing in the output window for about 5 minutes. Then the web app actually runs, and the following output shows in the IDEA output window:

/usr/local/tomcat7/bin/catalina.sh run

There's been a few posts about the line:

Artifact thought_test:war exploded: Server is not connected. Deploy is not available.

But none of the given solutions work. I can't see anything that's going on that looks like it's using a lot of resources, that would cause the delay. It's really odd because after the delay, the connection to the server works, even though initially it didn't.

Update:

I tracked it down to the firewall. In 'Security & Privacy' -> 'Firewall' -> 'Firewall Options...' I unchecked 'Enable stealth mode'. After I did that the app started right up in IDEA and the browser (Chrome). Note that I first added both IDEA and Chrome to the firewall's list of applications that 'Allow incoming connections' but that didn't matter.

I'd mark it as a solution, but I rather know why there's something in the Mac OS firewall that's treating the connection from IDEA to Tomcat as Ping or ICMP and blocking it for a few minutes.

What does your `run configuration` do before actually launching, eg run make or a maven build? Can you post a screeshot of the configuration window? You can also check the background tasks to see if something is running before tomcat (Window -> Background tasks -> Show) — Morfic, Jun 05 '15 at 14:13
Here's a screen shot of my run configuration: http://i59.tinypic.com/331q0r4.png -- all it's doing is 'make' and 'build artifact' that seems to happen in a second or so. Then the background tasks window just says "There are no active background tasks" — Hal50000, Jun 05 '15 at 14:26
How long does a build (e.g. `Build/Rebuild Project`) typically take? Same question for `Build/Build Artifacts/thought_test:war exploded/Rebuild`. — pens-fan-69, Jun 05 '15 at 14:38
One note on the `Server is not connected. Deploy is not available.` line: that is normal and is not the source of your problem. — pens-fan-69, Jun 05 '15 at 14:41
@pens-fan-69 `Build/Rebuild Project` takes under a second. For `Build/Build Artifacts/thought_test:war exploded/Rebuild` 92 ms. — Hal50000, Jun 05 '15 at 14:45
That's about 2/5 minutes. Any other background task running after these 2 and before starting tomcat? — Morfic, Jun 05 '15 at 14:49
@Morfic - how are you getting 2/5 minutes? It takes about two seconds for the `make` and `buld artifact`. After those happen there no background tasks at all for ~5 minutes. I checked `top` but didn't show much going on either. — Hal50000, Jun 05 '15 at 14:57
Apologies, I missed the `m` in the `ms`. Under the circumstances my next assumption would be that the _actual deployment_ takes that long. Anything else fishy on the deployment tab in the configuration window? How does it behave if you remove your artefact from the deployment list? — Morfic, Jun 05 '15 at 15:33
@Hal50000 Have you tried performing a `Build/BuildArtifacts/thought_test:war exploded/Clean` followed by a `Build/BuildArtifacts/thought_test:war exploded/Rebuild`? Also, you might want to check system logs to make sure you aren't getting retries on the disk or something weird like that. Another question that occurs is how much memory you have. Could you be in a situation where you are having to do massive swapping because of low available physical memory or because you have a large heap configured? — pens-fan-69, Jun 05 '15 at 16:01
I checked a little deeper. I'm just testing it out a jsp page. The jsp is in `$CATALINA_HOME/webapps/though_test/web/index.jsp`. When I hit run, the `before launch` settings `make` and then `build artifacts`. The path of the artifact build is `$CATALINA_HOME/thought_test/out/artifacts/thought_test_war_exploded/index.jsp` (and WEB-INF). The Tomcat instance run from IDEA runs the jsp in the `out`path. Everything in that directory is built almost immediately, *before* the ~5 minute wait. I thought about swapping being the issue. Any suggestions where to look for that in console? — Hal50000, Jun 05 '15 at 20:55

You need to increase your memory parameter.

Just go Run / Debug configuration and set is as in picture.Hope it will work better than previous

You might turn on the method breakpoints , find them and turn them off.

If you're using Tomcat plugin then make sure that in Tomcat Server configuration "Before Launch" doesn't contain the 'Build:artifcat' option as that's what makes it run every time even when you've done clean install.
