If use multithreaded IMAGEIO.read( File ) shows all kind of strange bugs including a complete vm crash. The crashdump is attached. This can be reproduces by starting (about?) 64 Threads and using IMAGEIO.read( File ) in an endless loop for random *but different* files. This programm must be run a few times since the crashes happen to appear shortly after starting it or not at all. Crashes happens in C [liblcms2.so.2+0x15480] cmsGetColorSpace+0x0 C [liblcms2.so.2+0x159b5] cmsSaveProfileToIOhandler+0x25 Code to reproduce: public static void main( String[] args ) throws Exception { for( int i=0; i<64; i++ ){ Thread t = new Thread( new ImageReader() ); t.start(); } } private static class ImageReader implements Runnable { @Override public void run() { int i=0; while( true ){ System.out.print( "." ); try { File f = findJpg(); ImageIO.read( f ); } catch( IOException e ) { throw new RuntimeException( e ); } i++; } } } private static File findJpg( File base ){ // Return a randomly chosen JPG from a larger pool } Reply at: https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/913434/comments/16 ------------------------------------------------------------------------ On 2014-08-08T12:27:21+00:00 Sgehwolf wrote: *** Bug 1897 has been marked as a duplicate of this bug. *** Reply at: https://bugs.launchpad.net/ubuntu/+source/openjdk-7/+bug/913434/comments/17 ------------------------------------------------------------------------ On 2014-08-10T15:59:32+00:00 Florian Bantner wrote: Seems this is a problem of liblcms2-2.5.
