STS 2.9.2 Won't Start

[danevaz]

Hi All,

Been using STS 2.9.2 (64 bit) w/o any problems for several months on WIN 7.

Yesterday (8/16) STS 2.9.2 would not start up - the green splash screen just hangs. WIN Task Manager shows program "Not Responding;" trying to run javaw.exe in C:Windows/System32. Did some on-line research and changed my STS.ini file's "osgi.requiredJavaVersion" from 1.5 to 1.6.

STS started up. Good!

Went home and came back in this AM. Tried to start STS 2.9.2 - hangs on splash screen again.

STS.ini:
-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1. 1.100.v20110502
-product
com.springsource.sts.ide
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
384M
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xmn128m
-Xms256m
-Xmx768m
-Xss1m
-XX:PermSize=128m
-XX:MaxPermSize=384m

After killing the hung process this STS window pops up:

Any ideas?

Thanks,

Hey Danny!

Hard to say from here what exactly caused this, but can you please try the following things:
- please start STS with the -clean option, maybe that helps
- if that doesn't help, please take a thread dump (first using jps to figure out the process ID of your running STS and then jstack to dump the state of the threads to the console), do this while STS is hanging, and attach the zipped thread dumps here, ok?

Martin,

Thanks for responding. Did try the -clear option as per other posts on this forum -no luck. Did some digging. Turns out my company's AntiVirus (SOPHOS) has a "real-time" scanner SavExec.exe that was churning away using between 25% and 50% of CPU - which was causing the start up of STS to effectively hang.

Work around was to temporarily stop the corresponding "SavExec" WINDOWS service while STS is starting up. Bingo - STS starts up just like before.

Why this problem didn't manifest itself previously is beyond me - SOPHOS must have changed something in their AV's settings.

Oh well... not the best solution but at least I can continue working.
