Designer Launcher Problem

Oracle introduced a regression/bug in Webstart with Java 7u9 which hasn’t been fixed yet. The only quick work-around for now is to edit the JNLP file and remove java-vm-args="-XX:MaxPermSize=128m" from any lines that contain it.

For example:

    <j2se version="1.6+" initial-heap-size="32M" max-heap-size="512M" java-vm-args="-XX:MaxPermSize=128m"/>
    <j2se version="1.5+" initial-heap-size="32M" max-heap-size="512M" java-vm-args="-XX:MaxPermSize=128m"/>

Would become:

    <j2se version="1.6+" initial-heap-size="32M" max-heap-size="512M" />
    <j2se version="1.5+" initial-heap-size="32M" max-heap-size="512M" />

You will then be able to launch by double-clicking the JNLP file for the time being.
