The JCK tests (ClassInterf02101, ClassInterf02301, ClassInterf02501, 
ClassInterf02801, ClassInterf02901, ClassInterf03301, ClassInterf03701, 
ClassInterf04001, ClassInterf04401, ClassInterf04501, ClassInterf04601, 
ClassInterf04801, ClassInterf04802, ClassInterf05601, ClassInterf05602, 
ClassInterf05701) using ClassLoader crash 1.2b3C JVM for WinNT.
All these tests crash jvm under the ClassLoader.defineClass() method
invocation.
For example, see the results of the ClassInterf02301 run:

? export CLASSPATH="H:\\ld32\\sqe\\harness_win\\classes;H:\\ld32\\for_WinNT\\classes"
? H:\\ld14\\java\\dest\\jdk1.2b3C\\win32\\bin\\java -verify javasoft.sqe.tests.vm.constantpool.ClassInterf023.ClassInterf02301.ClassInterf02301

EVALUATION This is caused by a silly typo in ClassLoader.c: TranslateToVMClassName was called on NULL names. *** /tmp/geta11704 Mon Jan 19 23:57:19 1998 --- ClassLoader.c Mon Jan 19 22:58:00 1998 *************** *** 109,120 **** utfName = buf; } (*env)->GetStringUTFRegion(env, name, 0, len, utfName); } else { utfName = NULL; } - TranslateToVMClassName(utfName); - result = (*env)->DefineClass(env, utfName, loader, body, length); if (utfName && utfName != buf) --- 109,119 ---- utfName = buf; } (*env)->GetStringUTFRegion(env, name, 0, len, utfName); + TranslateToVMClassName(utfName); } else { utfName = NULL; } result = (*env)->DefineClass(env, utfName, loader, body, length); if (utfName && utfName != buf)
