Question

当我尝试从Java 1.6（1.6.0_36）在Red Hat Enterprise Linux Server 6.4（Santiago）应用程序中运行JNLP时，我得到：

[wojtek@rcmtex05 ~]$ strace -e open
 /opt/tex/lib/java/jdk1.6.0_35/bin/javaws
 /tmp/app.jnlp >> 
 /home/wojtek/6.txt open("/etc/ld.so.cache", O_RDONLY)      = 3
 open("/usr/lib64/libX11.so.6", O_RDONLY) = 3
 open("/lib64/libnsl.so.1", O_RDONLY)    = 3 open("/lib64/libc.so.6",
 O_RDONLY)      = 3 open("/lib64/libdl.so.2", O_RDONLY)     = 3
 open("/usr/lib64/libxcb.so.1", O_RDONLY) = 3
 open("/usr/lib64/libXau.so.6", O_RDONLY) = 3
 open("/etc/nsswitch.conf", O_RDONLY)    = 3 open("/etc/ld.so.cache",
 O_RDONLY)      = 3 open("/lib64/libnss_files.so.2", O_RDONLY) = 3
 open("/etc/passwd", O_RDONLY|O_CLOEXEC) = 3
 open("/home/wojtek/.java/deployment/deployment.properties", O_RDONLY)
 = 3 open("/usr/lib/locale/locale-archive", O_RDONLY) = 3 open("/usr/lib64/gconv/gconv-modules.cache", O_RDONLY) = 3

但是当我尝试使用Java 1.7（1.7.0_65-b17）运行相同的应用程序时，结果是不同的：

为什么java 1.7会尝试加载这么多不同的新文件？

和gdb结果：

(gdb) exec-file /opt/tex/lib/java/jdk1.7.0_71/bin/javaws (gdb) set args /tmp/app.jnlp (gdb) run Starting program: /opt/tex/lib/java/jdk1.7.0_71/bin/javaws /tmp/app.jnlp

和JNLP文件看起来像：

Answer 1

解决方案是：向javaws添加任何param（例如-J或-Verbose）。
