The tableswitch is being generated for the enum switch (rtFields), but not the char switch. However, using the enum generates a ton of other invokes that will far outweigh any advantage of the tableswitch. It's possible the JIT is optimizing much of that away, but it's hard to tell without seeing the generated native code (a tricky thing to dig out). It's also possible the JIT could reorder the char switch into an indexed jump table even when javac doesn't, but again we'd need to see the native code to be sure. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
