Description

I tried to use the binary JRE bundle from the web site (jre-r468731) to run a hello world application.

I got error: java/lang/UnsatisfiedLinkError : Failed loading library "libhytext.so": DSO load failed

According to strace, the issue appears to be an inability to load the nonexistant libstdc+.so.5. By installing the gcc 3.3.4 compatibility libraries (compat-libstdc+-33 package), I was able to get it to work.

It would be good to document the needed library set or have a more meaningful error message than failure to load libhytext.so.

Another anomoly that appeared when running strace is that it appears to load BOTH libstdc+.so.6 AND libstdc+.so.5. This seems to be quite odd and seems to indicate that some components were compiled with one compiler and some other components were compiled with another compiler. It looks like libharmonyvm.so uses a current compiler while the hytext library uses an older compiler.

strace logs from the failure and after the legacy compatibility libraries were installed are attached.
