stopJarVerification

public static void stopJarVerification(java.lang.Object obj)

Stop JAR verification. Call once you have completed JAR verification.

getProviderList

beginThreadProviderList

public static ProviderList beginThreadProviderList(ProviderList list)

Methods to manipulate the thread local provider list. It is for use by JAR verification (see above) and the SunJSSE FIPS mode only. It should be used as follows: ProviderList list = ...; ProviderList oldList = Providers.beginThreadProviderList(list); try { // code that needs thread local provider list } finally { Providers.endThreadProviderList(oldList); }

endThreadProviderList

public static void endThreadProviderList(ProviderList list)
