Well, what do you know, java got bundled into last night's upgrade along
with 1 perl package upgrade.  When I checked, all was functioning
normally.  Go figure.  If something had become corrupted during the
first attempt, I would think that should be a bug in yum (it goes to
great extents to verify everything that gets updated before, during, and
after the update)!  But, this time, all is well, I am running the .75
packages without a hitch.

wow

Thanks for all the suggestions

I found my original update messages, and they said:

I hadn't realized that I went from .71 to .75 to .60 ..

I don't remeber exactly which ones, try at least java, javac and
libjavaplugin.so or something like that. For example, "sudo alternatives
--config java"

But also check you env vars. If you have PATH, LD_LIBRARY_PATH and/or
CLASSPATH changed they'll override alternatives selection.

Interesting suggestion.  I did note that I have been having
"alternative" warnings during previous updates of java openjdk, but
things were working properly.  What other packages might conflict?  How
do I check that the alternatives are set correctly?

Correct.  I was assuming that something was wrong at the system level.
Verified by the fact that after downgrading, everything started working
again.  Sounds like a bug to me.  I was wondering if anyone else saw the
same thing?

!?!?!?!?

Note the solution I'm looking for.  If this is a bug in the openjdk
packages, I want to help then figure it out and fix it.

Use "rpm --verify" to check for corruption before just blindly removing
and reinstalling packages.

Re: Latest Java-openjdk upgrade

[Fernando Lozano]

Hi,

I do heavy Java development and never had issues with OpenJDK on Fedora.
And I have OpenJDK on RHEL at many production sites. So don't bother
switching to Oracle Java. Instead try unistall and reinstall OpenJDK
Packages because it looks you have either a corrupted file.

Other option is you have other Java installations besides the
Fedora-provided OpenJDK and you PATH or CLASSPATH have entries for
different installations. This happen a lot when you have both GCJ and
OpenJDK or Oracle Java and OpenJDK. Maybe you left your browser install
Java (from Oracle) instead of configuring the Fedora-provided Java plugin.

Check which java, javac and etc are configured using alternatives and
check you env vars. Make sure you are using commands, jars and libraries
from the same installation.

Re: Latest Java-openjdk upgrade

[Angelo Moreschini]

Here a link that explains the *java.lang.ClassFormatError*:
http://craftingjava.blogspot.co.il/2012/07/reason-for-javalangclassformaterror.html


"*this error would be thrown when the java virtual machine attempts to read
a class file and founds that the class file has been altered in such a way
that it loses its integrity.*"

Here they are trying to say that *"if a class file has been modified in a
complicated way  then this error would be thrown." *

 There may be two possible ways a class file can get corrupted as far i
know.

 1.May be the compiler have some unresolved bugs in it.
2.The programmer may intentionally change the class file for some reasons.
--

In your case this error does not seem to depend on your code.

So, I can suggest you to use Oracle JDK instead OpenJDK, this because I had
some problems using NetBeans and then I got that suggestion, that helped me.
