my installer installs the JVM into directory /_jvm At JVM Settings -> Installer Settings I have set the option "Install Bundled".
I'd assume that the _jvm is always installed/overwritten, when the installer executes installation in the same directory. But unfortunality the _jvm is not overwritten.
It happens on all OSs. The log tells me only (I've translated the localized output) ... install directory: /foo/bar/_jvm status: success additional hint: directory already exists
install JRE: /foo/bar/_jvm status: success ...
But the files in the JRE are not changed. My "Default File Overwrite Behaviour" is set to "always overwrite".
Meanwhile I tried to configure, that the _jvm should be installed in $INSTALLER_TEMP_DIR$ and then during Install I add actions to move the /foo/bar/_jvm to /foo/bar/_jvm.bak and copy the $INSTALLER_TEMP_DIR$$/$_jvm to /foo/bar/_jvm. Unfortunality, the Move and Copy does not preserve the file permissions, so all execution bits gets lost. So Move and Copy are pretty useless in Unix environments without some kind of "preserve file permissions".
PS: I just recognized, that the Platforms -> Enable setting unix file permission was disabled, maybe this is the reason for loosing file permissions on copy/move.
