[jbosstools-issues] [JBoss JIRA] Commented: (JBDS-1150) Installer chooses 64-bit VM as the default VM even with 32-bit distribution

[Denis Golovin (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBDS-1150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12530205#action_12530205 ] 

Denis Golovin commented on JBDS-1150:
-------------------------------------

It happens because of the issue in JREPathPanel. It shows path to java used to run installer as default, but it should execute just "java" to initialize default path because it is what eclipse uses if there is no -vm option.

it means if you installer for win32 x86 started like

C:\Program Files (x86)\Java\jre6 -jar installer-win32.jar 

and it installs everything without errors with default java vm selected on step 4

JBDS might not start if default java is from C:\Program Files\Java\jre6


There is another issue in installer. It doesn't check that right java version x86 or x86_64 is used to run installer. It is critical for windows because installer for win32 contains only 32 bit version for dll's to create shortcuts and modify registry keys.

> At step 4 of 11, the default Java VM path points to C:\Program Files\Java\jre6.  However, it is a 64-bit VM which does not work with the 32-bit distribution.  If the default system JVM is 64-bit, the installer should ask user to specify the correct VM path or try to guess more paths (e.g. C:\Program Files (x86)\Java\jre6).  Otherwise, JBDS will fail on startup even if the installation succeeds.
