ESIntegTestCase has logic to clean up static fields in a method
annotated with
@AfterClass
so that these fields do not trigger theStaticFieldsInvariantRule. However, during the exceptional close of the
test cluster, this cleanup can be missed. The StaticFieldsInvariantRule
always runs and will attempt to inspect the size of the static fields
that were not cleaned up. If the
currentCluster
field ofESIntegTestCase references an InternalTestCluster, this could hold a
reference to an implementation of a
Path
that comes from thesun.nio.fs
package, which the security manager will deny access to.This casues additional noise to be generated since the
AccessControlException will cause the StaticFieldsInvariantRule to fail
and also be reported along with the actual exception that occurred.
This change clears the static fields of ESIntegTestCase in a finally
block inside the
@AfterClass
method to prevent this unnecessary noise.Closes #41526
