Subject [jira] [Updated] (KARAF-4976) JAVA_HOME autodiscovery not working on FreeBSD
Date Thu, 09 Feb 2017 19:12:41 GMT

     [ https://issues.apache.org/jira/browse/KARAF-4976?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eric de Boer updated KARAF-4976:
--------------------------------
    Attachment: java

I've attached the java wrapper sh script that FreeBSD uses to start Java, which also sets
JAVA_HOME

This should be the relevant code
{code}
_JAVAVM_PORTSDIR=
        if [ -r /usr/share/mk/bsd.port.mk ]; then
            _JAVAVM_PORTSDIR=`"${_JAVAVM_MAKE}" -f /usr/share/mk/bsd.port.mk -V PORTSDIR 2>/dev/null`
        fi

        _JAVAVM_BSD_PORT_MK=
        if [ -n "${_JAVAVM_PORTSDIR}" -a -r "${_JAVAVM_PORTSDIR}/Mk/bsd.port.mk" ]; then
            _JAVAVM_BSD_PORT_MK="${_JAVAVM_PORTSDIR}/Mk/bsd.port.mk"
        fi

        # If bsd.port.mk was found, use that to determine the VM to use.
        if [ -n "${_JAVAVM_BSD_PORT_MK}" ]; then
            JAVA_HOME=`"${_JAVAVM_MAKE}" -f "${_JAVAVM_BSD_PORT_MK}" -V JAVA_HOME USE_JAVA=yes
2>/dev/null`
            if [ -n "${JAVA_HOME}" -a -f "${JAVA_HOME}/bin/${_JAVAVM_PROG}" ]; then
                _JAVAVM_PROG_PATH="${JAVA_HOME}/bin"
                return 0
            elif [ -n "${JAVA_HOME}" -a \
                   -f "${JAVA_HOME}/jre/bin/${_JAVAVM_PROG}" ]; then
                _JAVAVM_PROG_PATH="${JAVA_HOME}/jre/bin"
                return 0
            fi
        fi
{code}

> If JAVA_HOME isn't set setenv tries to detect it from the path of java. On FreeBSD this
is /usr/local/bin/java,  while java resides in /usr/local/openjdk8/. This leads to setting
JAVA_HOME to a non existing path
> It would be nice to have it autodetect correctly, but at least check if the guessed JAVA_HOME
 is really a JDK/JRE, so it can be set correctly manually.
> Currently Karaf starts ok, but some functions that rely on a correct setting of JAVA_HOME
fail with unrelated error messages (e.g. doing a https call only throws a premaster secret
key error, because the Java ext dir is set incorrectly)
