Bug#894318: tomcat8 fail to find oracle jvm built with make-jpkg

[Daniele Palumbo]

Package: tomcat8
Version: 8.5.14-1+deb9u2
Severity: normal

Dear Maintainer,

tomcat8 has, in its init script, a lookup over the available jvm.
"""
     for jvmdir in /usr/lib/jvm/java-${java_version}-openjdk-* \
                      /usr/lib/jvm/jdk-${java_version}-oracle-* \
                      /usr/lib/jvm/jre-${java_version}-oracle-*
"""

the new make-jpkg has a different syntax, likely from version 0.61
>From http://metadata.ftp-master.debian.org/changelogs/contrib/j/java-package/java-package_0.62_changelog
"""
 * Use package name plus architecture as directory in /usr/lib/jvm
"""

to better understand the difference, see the following path of installation

old package path (jessie)
/usr/lib/jvm/jdk-8-oracle-x64/

new package path (stretch)
/usr/lib/jvm/oracle-java8-jdk-amd64/

The workaround as suggested also by the init script is to set JAVA_HOME variable indefault file.

A patch should be considered to properly lookup the new java package built.

Nevertheless, i would suggest to lookup the alternative jdk selected, in place of JAVA_HOME.
