getExecutor
public 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 classJreCompat- 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 foundjava.lang.SecurityException- If a security exception occurs while trying to identify the executorjava.lang.IllegalArgumentException- If the instance object does not match the class of the field when obtaining a field value via reflectionjava.lang.IllegalAccessException- If a field is not accessible due to access restrictions
