In the IPCFactory.java there is an assumption that the IPC arguments cannot have multiple equals characters. On Mac OS X , java.io.tmpdir points to a path that may have an equals character in it. In this case the IPC mechanism is completly broken and Plugin2 dies.

For example the argument to the child can be :

write_pipe_name=/var/folders/5s/bgzw1=tc658d0vqrjrd1s593++++fn/T/.com.sun.deploy.net.socket.-1.4567144119737929337.AF_UNIX


The fix for this problem is as below :


svn diff --depth empty -x -u -x -w 'src/plugin/share/classes/sun/plugin2/ipc/IPCFactory.java'
Index: src/plugin/share/classes/sun/plugin2/ipc/IPCFactory.java
