Nullpointer exception when use safari browser

[fcbflying]

Normally, it works fine. But if I click the send message button crazily in high frequency with safari brwoser. The NullPointerException will be thrown out from the method valueOfInner of class PacketType. But it works fine with other browsers ( firefox, chrome, ie). Any idea for this ? Thanks advanced.

[mrniko]

what about other browsers?

[fcbflying]

Other browsers works fine.Only for safari, this will happen.

[mrniko]

could you please switch debug level of "com.corundumstudio" to trace and publish this log?
