This is found in upgrade regression test in s10u4_01. This impact x86 only.

I did the follow install on x86:

OS: Solaris 10 Update 3 FCS
Media: DVD net image
Locales to install: C
Disk layout: ttinstall and use minimal required disk layout

Then I upgrade to s10u4_01 as follow:

OS: s10u4_01
Media: DVD net image
upgrade method: DVD upgrade and use upgrade with Disk Space reallocation

After the upgrade, pkgchk -n review the following error:

# pkgchk -n SUNWj5rtx
ERROR: /usr/jdk/instances/jdk1.5.0/jre/lib/amd64/j2pkcs11.dll
    pathname does not exist
ERROR: /usr/jdk/instances/jdk1.5.0/jre/lib/amd64/j2pkcs11_g.dll

If you look at SUNWj5rtx for x86 in s10u3 FCS, it had the following:

It had patch 118669-11 and the following files had been obseleted by the patch:

/usr/jdk/instances/jdk1.5.0/jre/lib/amd64/j2pkcs11.dll
/usr/jdk/instances/jdk1.5.0/jre/lib/amd64/j2pkcs11_g.dll

Looking at the .pkghistory for s10u4, all the Java 1.5 packages had VERSION=1000 and do pkgrm. However, SUNWj5rtx, SUNj5dvx and SUNWjvdmx does not have any entries to do pkgrm during upgrade. This should be fixed.

The .pkghistory for snv_57 also had similar issues as well and it should be fixed.
