This is a pre-release version. It may work for you, it may not.
The JRE1.1.5 SunOS binary (4,968,784 bytes) was built with Motif 1.2.1 on a SunOS 4.1.3_U1 system. Also available via FTP.
The gzipped tar file is 4,968,784 bytes, and unpacks to a directory of roughly 6.9Meg.
You will receive messages like
Warning: gethostbyname(xxx.xxx.xxx) not reentranton stderr. This will be fixed in a future release.
SunOS has no native support for Multicast networking.
cat jre1.1.5-FreeBSD.tar.gz | (cd /usr/local; gtar xvfzp -)
You will need X11R4 or later versions of the libX11, libXt, and libXext shareable libraries.
Sorry I can't guarantee any support, but you could try sending me problem reports via email.
