CachedDataAccessController.getSpectrumById() ClassCastException

[Tobias-Ternent]

In class: CachedDataAccessController

L166

Spectrum getSpectrumById(Comparable id, boolean useCache) {
    return useCache ? (Spectrum) cache.get(CacheEntry.SPECTRUM, id) : null;
}

This method is being used by the PX submission pipeline:

Spectrum spectrum = dataAccessController.getSpectrumById(specId);

java.lang.ClassCastException: java.util.Collections$SynchronizedMap cannot be cast to uk.ac.ebi.pride.utilities.data.core.Spectrum

So the cache.get() is returning a SynchonizedMap instead of just one Spectrum object.

@tobias can you add me an example where you found the problem, to be able to reproduce the error.

Should be address in the performance optimization.
