Windows install requires Java 6 (not Java 6 or 7) #719

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install Raptor98u3f5_w64.exe without installing Java 6.

What is the expected output? What do you see instead?
During the install process, the installer doesn't recognize that I have Java 7 
installed.
If I try to run Raptor.exe (or even java -jar Raptor.jar) with my existing Java 
7 install, it won't run (an exception occurs).

What version of the product are you using? On what operating system and
what environment?
Windows Vista Home Premium x64

Please provide any additional information below.
In theory Java 7 should be backward-compatible with Java 6 applications, so 
Raptor should be compatible with either Java 6 or Java 7.

After I install Java 6, I still observe:

I have the same problem.
Raptor doesn't even start anymore.

I have tried everything on windows 7 and on windows 8.
Please help because I really liked the program.
I think the problem started when the fics server where down and only the backup 
servers   worked.
Regards Jonathan

Based on that stack trace, it looks like maybe the problem has something to do 
with the UpdateManager.  Is there a way to launch Raptor with the UpdateManager 
disabled?  Maybe that would bypass the problem?

That's a great idea.  I have reinstalled Raptor (this time, the 64-bit version) 
and manually downloaded Raptor.jar to C:\Program Files\Raptor\Raptor.jar.  I'll 
try again tonight (from source code) since the following fails:
c:\Program Files\Raptor>java -jar Raptor.jar
Exception in thread "main" java.lang.NullPointerException
        at raptor.Raptor.shutdownWithoutExit(Unknown Source)
        at raptor.Raptor.shutdown(Unknown Source)

        at raptor.Raptor.main(Unknown Source)

An Eclipse build from source (swtEnv=Windows32 in build.xml) succeeds and 
connects to FICS using my preferences!

FYI, a "Windows64" build (which should work on my 64-bit OS) fails.  I'll see 
if I can figure this out:
run:
     [java] Exception in thread "main" java.lang.NullPointerException
     [java]     at raptor.Raptor.main(Raptor.java:222)
     [java] Java Result: 1

In order to run 32-bit Raptor on my 64-bit Windows machine, I had to update my 
Java preferences to define a 32-bit JRE via the following steps:
1. Run > "javaws -viewer"
2. Java > View > Find (or Add)
3. Find (or Add) an installed 32-bit JRE (can be a Java 7 JRE) from the 
C:\Program Files (x86)\Java directory.

I'm still curious and trying to figure out why 64-bit Raptor doesn't work on my 
machine, but I can confirm that 32-bit Raptor with a 32-bit JRE running on a 
64-bit Windows OS works (including the Updater working).

Thanks for the workaround.  I'm up and running with 32-bit Raptor now.

Before installing 32-bit Raptor, I tried to use the uninstaller for the 64-bit 
Raptor and got an error, for which I created Issue 736.  I'm not sure whether 
these two issues might be related.

I would recommend classifying this issue as an open low-priority Java 7 64-bit 
compatibility defect, for which there is a workaround (use the 32-bit version 
and require the user to figure out how to install 32-bit Java).
