No, if we are talking about APARs in general. Each APAR above corresponds to fixes for a subset of Java6_64 filesets; two such APARs are often for two different subsets of the filesets.
Yes, if we are talking about a particular fileset. All the changes in a fileset at v.r.m.f level is also in or is superseded by the changes in the fileset at a higher level.
How do I know if I have installed the latest code?
You can use the command /usr/java6_64/jre/bin/java -fullversion and compare the build date with the list above.
You can also use the command instfix -ivk APAR_NUMBER to check if the APAR is installed on your system.
Another way is to check fileset levels. You can run the command lslpp -L | grep Java6_64 to find out what Java6_64 filesets you have installed on your machine and at what levels. Then you can compare with the following information on latest fileset updates:
From IZ20752
Java6_64.sdk.6.0.0.25.bff (required)
Java6_64.source.6.0.0.25.bff
You only need to get updates for the filesets you need. For example, if you do not need Java6_64.samples or Java6_64.source fileset,
then you do not need any updates for those filesets. (Only the Java6_64.sdk fileset is required; the rest are optional.)
