• clearClassLoaderCaches

  public static void clearClassLoaderCaches()

  Cleans well known class loader leaks in VMs and libraries. There is a lot of bad code out there and this method will clear up the know problems. This method should only be called when the class loader will no longer be used. It this method is called two often it can have a serious impact on preformance.

• clearSunJarFileFactoryCache

  public static void clearSunJarFileFactoryCache(java.lang.String jarLocation)

• clearSunSoftCache

  public static void clearSunSoftCache(java.lang.Class clazz,
                                       java.lang.String fieldName)

  Clears the caches maintained by the SunVM object stream implementation. This method uses reflection and setAccessable to obtain access to the Sun cache. The cache Class synchronizes upon itself for access to the cache Map. This method completely clears the class loader cache which will impact preformance of object serialization.

  Parameters:

  clazz - the name of the class containing the cache field

  fieldName - the name of the cache field

• cleanOpenJPACache

  public static void cleanOpenJPACache(java.lang.ClassLoader classLoader)

• resourceName

  public static java.lang.String resourceName(java.lang.String s)

• configurer

  public static ClassLoaderConfigurer configurer(java.lang.String rawId)
