Ubuntu 10.04 and Bloom Facebook uploader

It seems that Bloom uploader Java webstart fails to authenticate in Ubuntu 10.04 with OpenJDK. To resolve this issue, I have created a file run.sh in the directory in the webstart cache folder (in my case '/home/myusername/.netx/cache/http/www.antaki.ca/bloom/jars'):

run.sh:

java -classpath Bloom_2_8_0.jar:BrowserLauncher2-1_3.jar:commons-codec-1.3.jar:commons-httpclient-3.1.jar:commons-logging-1.1.1.jar:facebook.jar:forms-1.3.0.jar:glazedlists_java15.jar:jhbasic.jar:json_simple.jar:metadata-extractor-2.3.1.jar:swing-worker-1.1.jar:swingx-1.0.jar ca.antaki.www.bloom.app.Bloom

When I start Bloom using run.sh it starts and authenticates just fine.
