This package has apparently never been stabilized yet, however it is quite bulletproof in my experience. All recent bugs are apparently issues with the ebuild itself, and there are no open bugs for a couple of months.
I'm fine with stabilization. 13 May 2012; Ralph Sennhauser <sera@gentoo.org> java-service-wrapper-3.5.14-r1.ebuild: Don't try to install nonexistent docs. #415703 *java-service-wrapper-3.5.14-r1 (03 May 2012) 03 May 2012; Ralph Sennhauser <sera@gentoo.org> +java-service-wrapper-3.5.14-r1.ebuild, +files/java-service-wrapper-3.5.14-gentoo-wrapper-defaults.patch: Don't resolve symlinks to run-java-tool. #414027 Drop base.eclass, bump EAPI and use java_prepare. Arch teams please stabilize =dev-java/java-service-wrapper-3.5.14-r1 There are no prior stable versions of this package. Target keywords are amd64 x86. Thanks.
