Does the directory with the application contain any non-ASCII character?

If so, then it is a known issue 119567 that is caused by a GlassFish

issue 3827. The workaround is to rename the directory to contain ASCII

letters only. See http://www.netbeans.org/issues/show_bug.cgi?id=119567

and https://glassfish.dev.java.net/issues/show_bug.cgi?id=3827 for more

details.

上面的意思是说在路径中存在中文，换了一个位置，果然成功。
