---------------------------------
Summary: Jsvc not loading correct shared lib for Java 7 on MacOS
Key: DAEMON-281
URL: https://issues.apache.org/jira/browse/DAEMON-281
Project: Commons Daemon
Issue Type: Bug
Components: Jsvc
Affects Versions: 1.0.13
Environment: MacOS 10.8.2 with Java 7:
$ java -version
java version "1.7.0_15"
Java(TM) SE Runtime Environment (build 1.7.0_15-b03)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
Reporter: Ian Emmons
When I try to run my program via jsvc, it complains:
Cannot find any VM in Java Home <<JAVA_HOME>>
Cannot locate JVM library file
where <<JAVA_HOME>> is set to
/Library/Java/JavaVirtualMachines/jdk1.7.0_15.jdk/Contents/Home
The -debug switch shows jsvc searching for several shared libraries in the
folder
$JAVA_HOME/../Libraries/
However, with Java 1.7 this folder does not exist, and jsvc should be trying to
load this:
$JAVA_HOME/jre/lib/server/libjvm.dylib
If I change JAVA_HOME to point to Apple's Java 1.6, then jsvc successfully
finds the JVM shared library.
Note: I built jsvc myself with no problems, and the output of the build makes
it clear that it used the Java 7 JNI headers in the compilation.
Background: Apple has deprecated Java 1.6. It not longer is present unless
the user explicitly installs it, and recent OS updates have disabled the
browser plugin and removed the Java control panel. Apple is pushing customers
toward's Oracle's Java 1.7.
