Java 7 interrompe l'applicazione SWT su OS X utilizzando Web Start

Abbiamo un'applicazione che si avvia tramite webstart che utilizza la libreria SWT.Java 7 interrompe l'applicazione SWT su OS X utilizzando Web Start

E 'ben noto che OSX richiede la libreria SWT per eseguire nel thread principale, quindi abbiamo questo nel nostro jnlp:

<resources os="Mac"> 
    <j2se version="1.6+" java-vm-args="-XstartOnFirstThread"/> 
    <jar href="swt-mac64.jar"/> 
</resources>

Dal momento che abbiamo trasferiti in Java 7 (1.7.0_10), è sembra che webstart non passi "-XstartOnFirstThread" al processo java che inizia.

Posso vedere da "ps" che il processo java non riceve l'opzione "-XstartOnFirstThread".

Qualcuno sa come ottenere webstart per tornare al suo comportamento precedente?

Cordiali saluti, Gord.

Questo è ciò che il registro webstart mostra:

Penso che Apple abbia usato per modificare la loro versione di java/javaws per consentire l'opzione -XstartOnFirstThread. Penso che Oracle non faccia quel passo in più da quando hanno assunto la distribuzione di java su mac. –

Il JNLP dichiara 'tutti i permessi'? Sono abbastanza sicuro che la richiesta verrebbe ignorata altrimenti. Assicurati di controllare il JNLP usando [JaNeLA] (http://pscode.org/janela/). –

Ho visto anche questo con Java 7 e mi chiedo se si tratta di un bug di Java 7 sulla base di questo post da un'altra persona (sono andato avanti e inviato un bug report dal momento che non ne ho visto nessuno dalla ricerca nel database dei bug di Java): http://www.java.net/forum/topic/jdk/java-se/webstart-os-x-xstartonfirstthread

La soluzione che ho trovato è semplicemente quella di usare javaws dal Java 6 fornito da Apple, anche se ho dovuto lanciarlo dalla riga di comando: /System/Library/Java/Support/Deploy.bundle/Contents/MacOS/javaws myjnlp.jnlp
