This bug is critical for us. Can it be fixed asap?
Bug is resolved by testing RPMs at: http://file.brq.redhat.com/~mmatejov/java-1.6.0-openjdk/RHEL-5_icedtea6-1.6/
(In reply to comment #8) > Bug is resolved by testing RPMs at: > http://file.brq.redhat.com/~mmatejov/java-1.6.0-openjdk/RHEL-5_icedtea6-1.6/ Thanks Martin! When we could expect this package in RHN?
That is really important bug while profiling the application... When can it be possible for RHEL5? Thanks...
This is fixed in the next RPMs, which are running the TCK as I write this.
The bug is still there on CentOS 5.6: java version "1.6.0_17" OpenJDK Runtime Environment (IcedTea6 1.7.10) (rhel-1.20.b17.el5-x86_64) OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode) java-1.6.0-openjdk.x86_64 1:1.6.0.0-1.20.b17.el5 installed
If you find yourself here because you are having the same problem on a recent version of RHEL, make sure you have the java-1.6.0-openjdk-debuginfo package installed.
Fixed in current release.
