Is there a mapping checklist for configuring my Java application?

How do I fix an unknown template for ordinal error?

When trying to create a recording of test that uses PowerMock either directly or indirectly (e.g. by using Mockito), you may see an error message similar to this one:

com.appland.appmap.record.UnknownEventException: unknown template for ordinal 1557
	at com.appland.appmap.record.EventTemplateRegistry.cloneEventTemplate(EventTemplateRegistry.java:89)
	at hudson.slaves.DelegatingComputerLauncherTest.testRecursionAvoidance(DelegatingComputerLauncherTest.java)

...

An unknown template for ordinal error happens when PowerMock uses its own ClassLoader to load the com.appland.* classes. To avoid this, you need to instruct PowerMock to ignore these classes. You can do this using the annotation @PowerMockIgnore("com.appland.*"), or by adding the entry

powermock.global-ignore=com.appland.*

to the PowerMock configuration file, as described here: https://github.com/powermock/powermock/wiki/PowerMock-Configuration#global-powermockignore . (Note that as of 20201124, there is an issue with the way that document describes ignoring multiple packages: https://github.com/powermock/powermock/issues/989.)
