Adding multiple contingencies in SensitivitiyAnalysis.add_postcontingency_branch_flow_matrix fails

[tso-martin]

Describe the current behavior

When I pass list with multiple contingency ids in
SensitivityAnalysis.add_postcontingency_branch_flow_factor_matrix I get an Exception:
PyPowsyblError: java.lang.ArrayIndexOutOfBoundsException: Index 444 out of bounds for length 444.

If I pass a list with a single contingency id it works.

Describe the expected behavior

The sensitivity analysis should be conducted for each contingency id.

Describe the steps

import pypowsybl.network as pn
from pypowsybl.sensitivity import create_dc_analysis
network = pn.create_ieee30()
gens = list(network.get_generators().index)
lines = list(network.get_lines().index)
contingencies = ["L8-28-1","L23-24-1"]
analysis = create_dc_analysis()
analysis.add_single_element_contingencies(contingencies)
analysis.add_precontingency_branch_flow_factor_matrix(branches_ids=lines, variables_ids=gens, matrix_id='precontingency')
analysis.add_postcontingency_branch_flow_factor_matrix(branches_ids=lines, variables_ids=gens, contingencies_ids=contingencies, matrix_id='postcontingency')
result = analysis.run(network)

Environment

PyPowSybl 1.7.0
Windows 10
