Method Detail- 
getExecutorpublic java.lang.Object getExecutor(java.lang.Thread thread) throws java.lang.NoSuchFieldException, java.lang.SecurityException, java.lang.IllegalArgumentException, java.lang.IllegalAccessExceptionDescription copied from class:JreCompatObtains the executor, if any, used to create the provided thread.- Overrides:
- getExecutorin class- JreCompat
- Parameters:
- thread- The thread to examine
- Returns:
- The executor, if any, that created the provided thread
- Throws:
- java.lang.NoSuchFieldException- If a field used via reflection to obtain the executor cannot be found
- java.lang.SecurityException- If a security exception occurs while trying to identify the executor
- java.lang.IllegalArgumentException- If the instance object does not match the class of the field when obtaining a field value via reflection
- java.lang.IllegalAccessException- If a field is not accessible due to access restrictions
 
 - 
isInstanceOfInaccessibleObjectExceptionpublic boolean isInstanceOfInaccessibleObjectException(java.lang.Throwable t) Description copied from class:JreCompatTest if the provided exception is an instance of java.lang.reflect.InaccessibleObjectException.- Overrides:
- isInstanceOfInaccessibleObjectExceptionin class- JreCompat
- Parameters:
- t- The exception to test

- trueif the exception is an instance of InaccessibleObjectException, otherwise- false
 
 - 
disableCachingForJarUrlConnectionspublic void disableCachingForJarUrlConnections() throws java.io.IOExceptionDescription copied from class:JreCompatDisables caching for JAR URL connections. For Java 8 and earlier, this also disables caching for ALL URL connections.- Overrides:
- disableCachingForJarUrlConnectionsin class- JreCompat
- Throws:
- java.io.IOException- If a dummy JAR URLConnection can not be created
 
 - 
addBootModulePathpublic void addBootModulePath(java.util.Deque<java.net.URL> classPathUrlsToProcess) Description copied from class:JreCompatObtains the URLs for all the JARs on the module path when the JVM starts and adds them to the provided Deque.- Overrides:
- addBootModulePathin class- JreCompat
- Parameters:
- classPathUrlsToProcess- The Deque to which the modules should be added
 
 - 
jarFileNewInstancepublic java.util.jar.JarFile jarFileNewInstance(java.io.File f) throws java.io.IOExceptionDescription copied from class:JreCompatCreates a new JarFile instance. When running on Java 9 and later, the JarFile will be multi-release JAR aware.- Overrides:
- jarFileNewInstancein class- JreCompat
- Parameters:
- f- The JAR file to open
- Returns:
- A JarFile instance based on the provided file
- Throws:
- java.io.IOException- If an I/O error occurs creating the JarFile instance
 
 - 
jarFileIsMultiReleasepublic boolean jarFileIsMultiRelease(java.util.jar.JarFile jarFile) Description copied from class:JreCompatIs this JarFile a multi-release JAR file.- Overrides:
- jarFileIsMultiReleasein class- JreCompat
- Parameters:
- jarFile- The JarFile to test
- Returns:
- trueIf it is a multi-release JAR file and is configured to behave as such.
 
 -

getModuleNamepublic java.lang.String getModuleName(java.lang.Class<?> type) Description copied from class:JreCompatWhat is the module of the given class?- Overrides:
- getModuleNamein class- JreCompat
- Parameters:
- type- The class to test
- Returns:
- Always truefor Java 8.trueif the enclosing package is exported for Java 9+
