Tests failing because of Leaked SDKs and sync roots issues.

All the tests were passing. Then we moved to a newer teamcity (on the cloud). Not sure about what exactly is the issue as I could not find any documentation related to Leaked SDKs issues

I am clearing the Sdk in tearDown() and the test start passing

SdkConfigurationUtil.removeSdk(systemJdk);

But there are still some tests that are failing with the following Throwable when clearing the Sdk. But just a few test fail now. Any ideas what is going on?

java.lang.Throwable: sync roots

Note: All tests are passing on the dev machine locally but failing on the new Teamcity cloud agents

Please see the lines in bold where Throwable: sync roots

Thanks for the help.
