Getting error when trying to use WebSphere 8.5.5

[zshahan]

I am getting this error below when starting WebSphere after adding glowroot. Is it something I did wrong?

Hi @zshahan, thanks for reporting this! It looks like Glowroot is not detecting that you are running WebSphere, and I'm not sure why. I added some debug logging to the latest snapshot release. Can you run with glowroot-agent-0.10.10-SNAPSHOT-dist.zip, and also increase the logging level by creating a file named glowroot.logback.xml in the glowroot folder with the contents below, and then post back with the new log?

glowroot.logback.xml contents:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration>
<configuration>
  <appender name="CONSOLE" class="org.glowroot.agent.shaded.ch.qos.logback.core.ConsoleAppender">

Sure thing. Attached is the new debug log.
glowroot.2018-05-17.log

Hi @zshahan, thanks for the debug log. I think this should be fixed now in the latest snapshot release glowroot-agent-0.10.10-SNAPSHOT-dist.zip.
