Subject [jira] Created: (GERONIMO-3446) Improperly configured JRE_HOME or JAVA_HOME environment variables can cause server failure

Improperly configured JRE_HOME or JAVA_HOME environment variables can cause server failure
------------------------------------------------------------------------------------------

                 Key: GERONIMO-3446
                 URL: https://issues.apache.org/jira/browse/GERONIMO-3446
             Project: Geronimo
          Issue Type: Bug
      Security Level: public (Regular issues)
    Affects Versions: 2.0
            Reporter: Kevan Miller
             Fix For: 2.0.x


If JAVA_HOME or JRE_HOME environment variables are not set properly, the Geronimo server may
fail during startup. For example, on Mac OS X, if you export JRE_HOME=/usr. You get the following:

Caused by: java.lang.NullPointerException
	at org.apache.geronimo.security.SubjectId.hashCode(SubjectId.java:79)
	at java.util.HashMap.hash(HashMap.java:264)
	at java.util.HashMap.put(HashMap.java:382)
	at java.util.Collections$SynchronizedMap.put(Collections.java:1983)
	at org.apache.geronimo.security.ContextManager.registerSubject(ContextManager.java:299)
	at org.apache.geronimo.security.ContextManager.<clinit>(ContextManager.java:71)
	... 37 more

The problem is that the java.ext.dirs property is being set to an improper value. This means
the JRE is not able to load jar files from $JRE_HOME/lib/ext.

At a minimum, our scripts should detect an invalid JRE_HOME or JAVA_HOME setting. Better yet,
we could try to set it automatically... In addition, it looks like we don't need to explicitly
configure the java.ext.dirs property any longer, anyway (we no longer package ext jars). Removing
the setting of the property (e.g.  -Djava.ext.dirs="$EXT_DIRS"  ) from our scripts would also
fix this specific problem...
