When adding resources using both MVEL and Java dialects the JavaDialect constructor fails when dialectData is found and stored.

In the constructor of JavaDialect, if pkg.getDialectRuntimeRegistry().getDialectData( ID ) returns a non null value, then a null is passed into the PackageStore constructor.

if ( pkg.getDialectRuntimeRegistry().getDialectData( ID ) == null )

{ data = new JavaDialectRuntimeData(); this.pkg.getDialectRuntimeRegistry().setDialectData( ID, data ); data.onAdd( this.pkg.getDialectRuntimeRegistry(), this.packageBuilder.getRootClassLoader() ); }

this.packageStoreWrapper = new PackageStore( data,
this.results );

is fixed by:

if (( data = (JavaDialectRuntimeData) pkg.getDialectRuntimeRegistry().getDialectData( ID )) == null ) { data = new JavaDialectRuntimeData(); this.pkg.getDialectRuntimeRegistry().setDialectData( ID, data ); data.onAdd( this.pkg.getDialectRuntimeRegistry(), this.packageBuilder.getRootClassLoader() ); }

this.packageStoreWrapper = new PackageStore( data, this.results );
