| Carl Mastrangelo A programming and hobby blog. Accidental Class Loading in Java Recently I’ve been working on improving the ergonomics of my tracing library PerfMark . One of the interesting things I noticed is that the JVM was loading some classes I didn’t expect it to. Let’s find out why! “That’s Weird” PerfMark works on much older JVM’s, but strives to be as fast as possible. To accomplish this, the code bootstraps itself based on what advanced JVM features are available ( MethodHandles , VarHandles , Hidden Classes , etc.). Because of this, the library needs to avoid loading classes that aren’t usable. In the event that no advanced features are available, the library safely disables itself. The code shows how to load optionally available classes safely: // SecretPerfMarkImpl.PerfMarkImpl static { Generator gen = null; Throwable problem = null; try { Class> clz = Class.forName( "io.perfmark.java7.SecretMethodHandleGenerator$MethodHandleGenerator"); gen = |
