[jbosstools-issues] [JBoss JIRA] (JBDS-3450) installer uses a specific JDK as default when installing JBDS; when user updates to newer rpm, jbdevstudio.ini points to non-existent path

[Denis Golovin (JIRA)]

    [ https://issues.jboss.org/browse/JBDS-3450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13074870#comment-13074870 ] 

Denis Golovin commented on JBDS-3450:
-------------------------------------

Possible approach is to run "java -version" and if it fails disable "Default Java VM" add warning at the left of radio "(not found)" or "(not detected)" and fall back to select Specific VM with path initialized from system property "java.home" of current VM.

> (2015-06-02 16:37:24) joshuaw: maxandersen: I just ran into an issue with JBDS if you have a min
> (2015-06-02 16:38:36) joshuaw: I'm running Fedora 22 and it wanted to update, so I let it. I think I had JBDS running when I restarted. When I restarted I couldn't start JBDS.
> (2015-06-02 16:39:02) joshuaw: I got the following error: A Java Runtime Environment (JRE) or Java Development Kit (JDK)
> (2015-06-02 16:39:02) joshuaw: must be available in order to run Jbdevstudio. No Java virtual machine
> (2015-06-02 16:39:02) joshuaw: was found after searching the following locations:
> (2015-06-02 16:39:02) joshuaw: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.45-38.b14.fc22.x86_64/bin/java
> (2015-06-02 16:39:31) nickboldt: does  your ~/jbdevstudio/*.ini file point to a SPECIFIC path for java?
> (2015-06-02 16:39:40) joshuaw: let me check
> 16:40
> (2015-06-02 16:40:10) nickboldt: if alternatives replaced the old JDK w/ newer one the problem is prolly that you're looking in a SPECIFIC place for JVM and Eclipse/JBDS can't find it
> (2015-06-02 16:41:37) joshuaw: though the OS update may have moved something :(
> (2015-06-02 16:42:10) nickboldt: does /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.45-38.b14.fc22.x86_64/bin/java exist?
> (2015-06-02 16:42:15) joshuaw: nickboldt: yeah, that location is in the .ini file
> (2015-06-02 16:42:28) nickboldt: and it actually exists on your disk after the update?
> (2015-06-02 16:42:29) joshuaw: nickboldt: that location does not exist 
> (2015-06-02 16:42:32) nickboldt: aha
> (2015-06-02 16:42:45) nickboldt: cd  /usr/lib/jvm/java-1.8.0-openjdk-1.8*
> (2015-06-02 16:42:48) nickboldt: pwd
> (2015-06-02 16:42:52) nickboldt: put that in your ini file
> (2015-06-02 16:45:46) joshuaw: I had /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.45-38.b14.fc22.x86_64/bin/java in the .ini file
> (2015-06-02 16:45:56) rbenevides is now known as rbenevides|afk
> (2015-06-02 16:46:03) joshuaw: and the system now has 1.8.0.45-39
> (2015-06-02 16:46:19) joshuaw: funny how java -version doesn't list the -39
> (2015-06-02 16:46:33) joshuaw: stupid minor minor version update
> (2015-06-02 17:46:43) maxandersen: joshuaw: any chance if you recall when you installed if you chose to use the default or specific version of a idk  ? 
> (2015-06-02 17:47:00) maxandersen: joshuaw: if used default it would be a bug if we added specific javavm to the ini file
> (2015-06-02 17:55:19) nickboldt: maxandersen: I never pick a specific one, just use default suggestion
> (2015-06-02 17:55:27) nickboldt: and I have $➔ cat studio/jbdevstudio.ini 
> (2015-06-02 17:55:27) nickboldt: -vm
> (2015-06-02 17:55:27) nickboldt: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.71-2.5.3.0.fc20.x86_64/jre/bin/java
> (2015-06-02 17:55:36) maxandersen: thats bad
> (2015-06-02 17:55:40) nickboldt: so... maxandersen... BUG. :(
> (2015-06-02 17:56:19) maxandersen: nickboldt: can you open bug for that one ?

> It's possible the installer is using the CURRENT value of alternatives path for JDK...
> {code}
> $➔ alternatives --display java
> java - status is manual.
>  link currently points to /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.71-2.5.3.0.fc20.x86_64/jre/bin/java
> /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.71-2.5.3.0.fc20.x86_64/jre/bin/java - priority 170071
> {code}
> So we need to maybe point to a different path... say, in /usr/lib/jvm/jre/ ?
