Error loading bin file

[raj hyd]

i have a certain requirement like if plugin1 is down plugin2 has to be called,both plugin1 and plugin2 uses same 3rd party api for plugin implementation.But when my plugin1 is down i am getting error with plugin2 like
"Error loading resource file: challenge.bin"
This challenge.bin is in 3rd party api used for plugin1 and plugin2 implementation.

Error loading resource file: challenge.bin
java.lang.NullPointerException
at java.io.FilterInputStream.available(Unknown Source)
