static Method	getAddNullUnsupportedMethod()	Returns the Method instance for testAdd_nullSupported() so that tests of TreeSet can suppress it with FeatureSpecificTestSuiteBuilder.suppressing() until JDK-5045147 is fixed.
static Method	getAddUnsupportedNotPresentMethod()	Returns the Method instance for testAdd_unsupportedNotPresent() so that tests can suppress it with FeatureSpecificTestSuiteBuilder.suppressing() while we figure out what to do with ConcurrentHashMap support for entrySet().add().

protected void	resetCollection()
protected Collection<E>	resetContainer(Collection<E> newContents)	Replaces the existing container under test with a new container.

getAddNullSupportedMethod

@GwtIncompatible
public static Method getAddNullSupportedMethod()

Returns the Method instance for testAdd_nullSupported() so that tests of Collections.checkedCollection(java.util.Collection, Class) can suppress it with FeatureSpecificTestSuiteBuilder.suppressing() until JDK-6409434 is fixed. It's unclear whether nulls were to be permitted or forbidden, but presumably the eventual fix will be to permit them, as it seems more likely that code would depend on that behavior than on the other. Thus, we say the bug is in add(), which fails to support null.

getAddNullUnsupportedMethod

@GwtIncompatible
public static Method getAddNullUnsupportedMethod()

Returns the Method instance for testAdd_nullSupported() so that tests of TreeSet can suppress it with FeatureSpecificTestSuiteBuilder.suppressing() until JDK-5045147 is fixed.

getAddUnsupportedNotPresentMethod

@GwtIncompatible
public static Method getAddUnsupportedNotPresentMethod()

Returns the Method instance for testAdd_unsupportedNotPresent() so that tests can suppress it with FeatureSpecificTestSuiteBuilder.suppressing() while we figure out what to do with ConcurrentHashMap support for entrySet().add().
