Description:
After configuring HKAM for AMX/BPM, the host microagent will appear on the Hawk Display. After installing AMX 3.3.0 HF-12 or above, this is no longer the case.

Symptoms:
Hawk Agent shows a stack trace upon startup causing the AMX plugin to fail to initialize. The exception below can be found in the Hawk.log file under the "<TIBCO_CONFIG_HOME>\cfgmgmt\hawk\logs" directory.

Cause:
This is a known issue awaiting a fix. The cause is that the application of AMX 3.3.0 Hotfix-12 or above incorrectly modifies a few classpaths in the Hawk HMA file.

The workaround is to replace the JAR files in the hawkamxhpa-Admin-amxadmin-AdminHost.hma to use older JAR files. To resolve the issue, open hawkamxhpa-Admin-amxadmin-AdminHost.hma and replace new JAR versions with old ones that are part of 3.3.0 HF-10. Here is the block in the .hma file that needs to be replaced.

<classpath>
<TIBCO_HOME>/components/shared/1.0.0/plugins/com.tibco.hawk.microagent.amx.common_1.3.9.001.jar</path>
<TIBCO_HOME>/components/shared/1.0.0/plugins/com.tibco.hawk.microagent.amx.hpa_1.3.9.001.jar</path>
<TIBCO_HOME>/components/shared/1.0.0/plugins/com.tibco.hawk.microagent.amx.service_1.3.9.002.jar</path>
</classpath>

The old JAR versions, which were previously used in the hawkamxhpa-Admin-amxadmin-AdminHost.hma files.

<classpath>
<TIBCO_HOME>/components/shared/1.0.0/plugins/com.tibco.hawk.microagent.amx.common_1.3.8.001.jar</path>
<TIBCO_HOME>components/shared/1.0.0/plugins/com.tibco.hawk.microagent.amx.hpa_1.3.8.001.jar</path>
<TIBCO_HOME>/components/shared/1.0.0/plugins/com.tibco.hawk.microagent.amx.service_1.3.8.001.jar</path>
</classpath>
