EVALUATION I cannot reproduce this bug under jvm111_18n. I have attached the files I used for testing, a modified HelloWorldApp and a shell script. Please check what version of java you are using with "java -fullversion" and then examine my test case and see if this is reasonable for your original bug. $ cat xH.java /** * The HelloWorldApp class implements an application that * simply displays "Hello World!" to the standard output. */ class H\u30d0lloWorldApp { public static void main(String[] args) { System.out.println("Hello World!"); //Display the string. } } $ javac xH.java $ yy=$(echo H*) $ echo $yy H����lloWorldApp.class $ java ${yy%%.*} Hello World! $ ###@###.###da 1997-05-14 The java vm version is like below; global% java -fullversion java full version "jvm111_16n:97.04.15" global% uname -a SunOS global 5.6 s297_32 sun4u sparc SUNW,Ultra-2 And this problems seems happen on any java file which has more than one class.
