```
public final class JavaUtils
extends Object
```
Collection of Java class loading/reflection related utilities common across Hive.

Methods
Modifier and Type	Method and Description
`static void`	`closeClassLoader(ClassLoader loader)`
`static boolean`	`closeClassLoadersTo(ClassLoader current, ClassLoader stop)`
`static ClassLoader`	`getClassLoader()` Standard way of getting classloader in Hive code (outside of Hadoop).
`static Class`	`loadClass(String className)`
`static Class`	`loadClass(String className, boolean init)`
`static String`	`lockIdToString(long extLockId)` Utility method for ACID to normalize logging info

getClassLoader
```
public static ClassLoader getClassLoader()
```
Standard way of getting classloader in Hive code (outside of Hadoop). Uses the context loader to get access to classpaths to auxiliary and jars added with 'add jar' command. Falls back to current classloader. In Hadoop-related code, we use Configuration.getClassLoader().

public static Class loadClass(String className)
                       throws ClassNotFoundException

public static Class loadClass(String className,
              boolean init)
                       throws ClassNotFoundException

public static boolean closeClassLoadersTo(ClassLoader current,
                          ClassLoader stop)

public static void closeClassLoader(ClassLoader loader)
                             throws IOException
