Comments

EVALUATION The crash appears to be caused by moving i18n converters into the extension directory. This is a bootstrap problem. In the Japanese locale, sun.io.ByteToCharConverter failed to load because somehow its static initializer requires the *VM* class loader to load CharToByteEUCJIS class (the class name passed to the findSystemClass0 method at the top of stack trace below). Note that all this happens before the extension class loader is even constructed. (dbx) print printStackTrace(EE(), 1000) at java.lang.ClassLoader.findSystemClass0(Native Method) at java.lang.ClassLoader.findSystemClass(ClassLoader.java:371) at java.lang.ClassLoader.loadClass(ClassLoader.java:228) at java.lang.ClassLoader.loadClass(ClassLoader.java:179) at sun.io.CharToByteConverter.getConverterClass(CharToByteConverter.java :101) at sun.io.CharToByteConverter.getDefaultConverterClass(CharToByteConvert er.java:119) at sun.io.CharToByteConverter.<clinit>(CharToByteConverter.java:72) at java.lang.String.getBytes(String.java:539) at java.io.File.list0(Native Method) at java.io.File.list(File.java:760) at sun.misc.ExtClassLoader.getExtURLs(ExtClassLoader.java:74) at sun.misc.ExtClassLoader.<init>(ExtClassLoader.java:43) at sun.misc.ExtClassLoader.<init>(ExtClassLoader.java:36) at sun.misc.Launcher.getExtClassLoader(Launcher.java:264) at sun.io.ByteToCharConverter.getConverterClass(ByteToCharConverter.java :98) at sun.io.ByteToCharConverter.getDefaultConverterClass(ByteToCharConvert er.java:118) at sun.io.ByteToCharConverter.<clinit>(ByteToCharConverter.java:71) at java.lang.System.initProperties(Native Method) at java.lang.System.initializeSystemClass(System.java:664) The reason for the crash is that the VM fails to deal with a failure condition on loading ByteToCharConverter at start-up time. This is part of the somewhat ugly makeJavaStringFromPlatformCString code left over from 1.1 time: byteToChar = (Hsun_io_ByteToCharConverter *) execute_java_static_method (ee, FindClass(ee, "sun/io/ByteToCharConverter", TRUE), "getConverter", "(Ljava/lang/String;)Lsun/io/ByteToCharConverter;", makeJavaString(encoding, strlen(encoding))); Note that the result value of FindClass(ee, "sun/io/ByteTo...) is not checked. sheng.liang@Eng 1998-01-30 BTW, this bug is reproducible by running any Java program under the "ja" (and I suspect any other foreign) locale. You don't have to run Hotjava. However, you need to run it on a machine with "ja" locale installed, such as Norbert's machine (called lindenberg). sheng.liang@Eng 1998-01-30
