The 'etc' and 'deploy' directories are under subversion control. Karaf sees the '.svn' in 'deploy' as a bundle and creates a generated module called '.svn.jar'. When I do an update to 'deploy' the files under 'deploy/.svn' are changed and the generated bundle gets changed. At this about this time fileinstall attempts to open the file '.svn.jar' with new JarFile(file) and sometimes this cause a SIGBUS error in the JVM. The '.svn.jar' is the only jar file, fileinstall attempt to open and it is on this line the JVM dies.
I have logged the follow errors to Sun. But I am trying to put in a work around as I don't know how long that might take. ;) The same bug appears on Solaris x86 and SUSE 10. # # A fatal error has been detected by the Java Runtime Environment: # # SIGBUS (0xa) at pc=0xfe291ce0, pid=23367, tid=67 # # JRE version: 6.0_16-b01 # Java VM: Java HotSpot(TM) Server VM (14.2-b01 mixed mode solaris-x86 ) # Problematic frame: # C [libzip.so+0x1ce0] # Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [libzip.so+0x1ce0] C [libzip.so+0xb1a2] C [libzip.so+0x25a8] Java_java_util_zip_ZipFile_open+0xb8 j java.util.zip.ZipFile.open(Ljava/lang/String;IJ)J+0 j java.util.zip.ZipFile.<init>(Ljava/io/File;I)V+98 j java.util.jar.JarFile.<init>(Ljava/io/File;ZI)V+3 j java.util.jar.JarFile.<init>(Ljava/io/File;)V+4 j org.apache.felix.fileinstall.internal.BundleTransformer.canHandle(Ljava/io/File;)Z+74 -----Original Message----- From: Guillaume Nodet [mailto:[email protected]] Sent: 16 November 2009 13:56 To: [email protected] Subject: Re: If you see locking and nothing else...

This should not happen, as fileinstall makes sure the content does not change before actually loading the jar (or it tries to).
