[7u4] Request for approval for CR: 7142667: Problems with the value passed to the 'classes' param of JavaCompiler.CompilationTask.getTask(...)

[Jim Holmlund]

Request for Backport of a JDK 8 fix into 7u4.


Bug description  :     http://monaco.us.oracle.com/detail.jsf?cr=7142667/7u4


The fix  is the same as in JDK 8:
    JDK 8 changeset :   http://hg.openjdk.java.net/jdk8/tl/langtools/rev/237198ef45f5

It is basically a one line fix that avoids an assert failure on illegal code so that a proper error 
msg can be generated instead.

The fix has passed the JDK 8 nightly tests.
