Classpath 0.90 makes the Jmol application run

A few days back, Classpath 0.90 was released, the first release after the 0.20 release. Earlier Classpath releases could run the rendering engine , but running the application failed so far .

Today it hit Debian unstable, so upgrade my sid32 chroot and had Cacao run Jmol. I had some memory issues opening a small molecule (4-methyl-2-pentyne), and the rendering speed was a factor 100 or so slower than Sun’s JVM, but it runs!

Using the command cacao -Xmx512M -jar Jmol.jar triplebond.mol I got results.

Note the exceptions copied to the console. Many thanx to the Classpath team!
