sometimes there is more information on the deadlock at the bottom of the thread dump (i think) including what thread was deadlocked with what...

I'm having problem with SUN jdk 1.4.2. My application deadlocks when its trying to find the file size. When I do a strace -p pid, this is the output I get
futex(0x9e21ff88, FUTEX_WAIT, 0, NULL)
The thread dump shows the following:
"RMI TCP Connection(1206)-10.0.102.3" daemon prio=1 tid=0xaa1125f0 nid=0x4690 waiting for monitor entry [a15a1000..a15a2854] at java.io.ExpiringCache.get(ExpiringCache.java:50) - waiting to lock <0x4ad90d78> (a java.io.ExpiringCache) at java.io.UnixFileSystem.canonicalize(UnixFileSystem.java:137) at java.io.File.getCanonicalPath(File.java:513) at java.io.FilePermission$1.run(FilePermission.java:218) at java.security.AccessController.doPrivileged(Native Method) at java.io.FilePermission.init(FilePermission.java:212) at java.io.FilePermission.<init>(FilePermission.java:264) at java.lang.SecurityManager.checkRead(SecurityManager.java:863) at java.io.File.length(File.java:791) at com.zantaz.base.archiver.FileProxy.getSizeFromDisk(FileProxy.java:496)
This app used to work without any problem in jdk1.3. Does anyone have any clue ??
