Daniel Collins commented on SOLR-6693:
--------------------------------------
Yeah, I was half-joking and half-serious when I suggested JVM re-install.
Windows JVM installs always seem somewhat prone to needing a re-install from
time to time, The {{C:\Windows\System32\java.exe}} always seems to favour the
"last" JVM you installed as well, so if you have (for example) a Java 7 and
Java 8 JVM installed, and then you update your Java 7 JVM, that becomes the new
"default". You have to re-update Java 8 to update that magic version of
{{java.exe}}.
It always makes me glad to get back to Linux every time I have to use Windows,
at least there applications get installed into directories, if they are on your
path (or I explicitly run them), they get used, if they aren't, they don't. It
makes so much more sense that way :-)

> Key: SOLR-6693
> URL: https://issues.apache.org/jira/browse/SOLR-6693
> Project: Solr
> Issue Type: Bug
> Components: scripts and tools
> Affects Versions: 4.10.2
> Environment: WINDOWS 8.1
> Reporter: Jan Høydahl
> Labels: bin\solr.cmd
> Fix For: 5.0, Trunk
>
>
> *Reproduce:*
> # Install JRE8 from www.java.com (typically {{C:\Program Files
> (x86)\Java\jre1.8.0_25}})
> # Run the command {{bin\solr start -V}}
> The result is:
> {{\Java\jre1.8.0_25\bin\java was unexpected at this time.}}
> *Reason*
> This comes from bad quoting of the {{%SOLR%}} variable. I think it's because
> of the parenthesis that it freaks out. I think the same would apply for a
> 32-bit JDK because of the (x86) in the path, but I have not tested.
> Tip: You can remove the line {{@ECHO OFF}} at the top to see exactly which is
> the offending line
> *Solution*
> Quoting the lines where %JAVA% is printed, e.g. instead of
> {noformat}
> @echo Using Java: %JAVA%
> {noformat}
> then use
> {noformat}
> @echo "Using Java: %JAVA%"
> {noformat}
> This is needed several places.
