Description Marc Schoenefeld 2011-03-21 14:42:38 UTC
The blog post on 
http://slightlyrandombrokenthoughts.blogspot.com/2011/01/trusted-method-chaining-to-systemexit.html describes how to construct a trusted method chain that calls into System.exit . While it could be difficult to workaround the general problem of trusted method chains, an straightforward fix for this would be to 

* replace the System.exit call with throwing an IllegalArgumentException in com.sun.org.apache.bcel.internal.classfile.Utility.codeToString() 

so attackers would not be able anymore to shut down the JVM.

Looks like Oracle hasn't urgent plans to fix this, so this security patch will need propagation upstream into OpenJDK code source.

FWIW, I can't see the problem code in the version of JAXP imported into OpenJDK 6 on 2013-05-17 or OpenJDK 7 on 2011-12-22
