Returns the name of the Just-in-time (JIT) compiler.

  Returns the name of the Just-in-time (JIT) compiler.
Returns: the name of the JIT compiler.

  Returns the approximate accumlated elapsed time (in milliseconds) spent in compilation.

  Returns the approximate accumlated elapsed time (in milliseconds) spent in compilation. If multiple threads are used for compilation, this value is summation of the approximate time that each thread spent in compilation.

This method is optionally supported by the platform. A Java virtual machine implementation may not support the compilation time monitoring. The CompilationMXBean.isCompilationTimeMonitoringSupported() method can be used to determine if the Java virtual machine supports this operation.

This value does not indicate the level of performance of the Java virtual machine and is not intended for performance comparisons of different virtual machine implementations. The implementations may have different definitions and different measurements of the compilation time.
Returns: Compilation time in milliseconds
Throws:
- java.lang.UnsupportedOperationException - if the Java virtual machine does not support this operation.

  Tests if the Java virtual machine supports the monitoring of compilation time.

  Tests if the Java virtual machine supports the monitoring of
compilation time.
Returns: true if the monitoring of compilation time is supported ; false otherwise.
