http://nagoya.apache.org/bugzilla/show_bug.cgi?id=17287 Attempts to use the system class loader may crash the JVM. Summary: Attempts to use the system class loader may crash the JVM. Product: Ant Version: 1.5.1 Platform: All OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Core AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] My build script makes a call to execute (java) a small program I have written that calls the system ClassLoader to load a resource from a file. The problem is that the AntClassLoader gets called and craps out somewhere in native code for retrieving data from zip files. I have tested this under Java 1.3.1 for Windows, Java 1.4.1 for Windows, HotSpot 1.3.1 for MacOS X and HotSpot 1.4.1 for MacOS X. I have had the same results from all implementations. The program executes perfectly outside of Ant using the normal class loader. The following is a log dump from MacOS X with HotSpot 1.4.1: An unexpected exception has been detected in native code outside the VM. Unexpected Signal : Bus Error occurred at PC=0x9605A94C Function=[Unknown.] Library=/System/Library/Frameworks/JavaVM.framework/Versions/1.4.1/Libraries/libzip.jnilib NOTE: We are unable to locate the function name symbol for the error just occurred. Please refer to release documentation for possible reason and solutions.
