Running groovy webtests from Maven seems to hang at wt.htmlReports

I have a Maven project which features a handful of Groovy WebtestCases that I wrote (each extends com.canoo.webtest.WebtestCase). I am running these tests during the integration-test phase (I've bound an execution of failsafe test runner to the integration-test phase, and the groovy classes are compiled with the gmaven-plugin).

After the tests (which fail, btw) are run, the wt.htmlReports step seems to hang forever (this is on a Windows XP machine):

Tests in error:
testLoginSuccess(com.blah.LoginTest)
testHomePage(com.blah.HomePageTest)

Tests run: 2, Failures: 0, Errors: 2, Skipped: 0

wt.htmlReports:
    [mkdir] Created dir: C:\Documents and Settings\...\target\test-classes\webtest-results\resources
     [copy] Copying 20 files to C:\Documents and Settings\...\target\test-classes\webtest-results\resources
     [xslt] Transforming into C:\Documents and Settings\...\target\test-classes\webtest-results
     [xslt] Transforming into C:\Documents and Settings\...\target\test-classes\webtest-results

("..." is not the real path)

Taking a look at the process in Process Explorer, the process seems to keep a file handle open to target\test-classes\webtest-resources\tools\spinner.gif. If I kill the Maven process, then any subsequent attempts to clean the project result in an error that this file is still locked.

Looking at the process in Visual VM, I see a thread related to groovy/WebTestMonitorImpl which seems to be dead-locked waiting for a java.awt.EventQueue$1AWTInvocationLock:

...

I've attached the complete thread dump.

Is it possible there is some sort of deadlock going on while copying the resources to the target directory? Has anyone seen this before?

Relevant version info:
