Description

If there is a parsing error in one of the rule files in KeY,
KeY does not load, but does not report an error. Only in the status line
it reports

Failed to load JML specifications

This is a false error report.

Reproducible

Reproducible

Steps to reproduce

Go and touch one file in key.core/src/main/resources/de/uka/ilkd/key/proof/rules/ such that it contains
a syntax error.

This error should be reported. But it is not.

Additional information

Debugging reveals that the URL string is

file://jar:file:/home/SOMEPATH/key/key/key.core/build/libs/key.core-2.7.jar!/de/uka/ilkd/key/proof/rules/javaRules.key

which is bound to fail
