Sebb updated DAEMON-102:
------------------------
Fix Version/s: 1.0.2
> JVM + System PATH environment = Version Skew
> --------------------------------------------
>
> Key: DAEMON-102
> URL: https://issues.apache.org/jira/browse/DAEMON-102
> Project: Commons Daemon
> Issue Type: Bug
> Affects Versions: 1.0 Alpha, 1.0, 1.0.1
> Environment: Windows, All
> Reporter: Bob Kerns
> Fix For: 1.0.2
>
>
> When Tomcat 6 is installed, it prompts you for the location of the JVM you
> wish to use.
> However, it neither computes the necessary value for the PATH environment
> variable to make that JVM work, nor prompts you for it.
> Instead, it depends on the system's PATH environment variable happening to
> have on it the JRE's bin directory.
> If, however, it does not have a JRE bin directory, or it points to a
> DIFFERENT JRE -- we have a problem.
> Basically, this is a formula for very mysterious failure. When the System
> path changed, due to a change in JVM for other purposes, Tomcat 6's service
> launcher mysteriously became unable to load the JVM.
> My workaround was to add the Environment configuration parameter with PATH=<a
> valid path>. (I did this via editing the registry; presumably I could have
> done it from the command line. But the GUI does NOT provide a way to set
> this!)
> It seems wrong to always embed the ENTIRE pah. Perhaps when launching a JVM
> it should silently do a SetDllDirectory to add the parent directory. This
> would ensure that it would find the CORRECT dlls. The current behavior does
> NOT find the correct DLLs unless (and while) the system PATH variable points
> to them.
> This makes the behavior consonant with what running the JVM from java.exe
> does, because the .exe's directory (same as the parent of the jvm.dll's
> directory) is automatically included in the DLL search path, earlier than the
> PATH variable.
