Example 1 with InvalidIdGeneratorException

use of org.neo4j.kernel.impl.store.InvalidIdGeneratorException in project neo4j by neo4j.

the class IdGeneratorImplTest method shouldForceStickyMark.

@Test
public void shouldForceStickyMark() throws Exception {
    // GIVEN
    try (FileSystemAbstraction fs = new DefaultFileSystemAbstraction()) {
        File dir = new File("target/test-data/" + getClass().getName());
        fs.mkdirs(dir);
        File file = new File(dir, "ids");
        fs.deleteFile(file);
        IdGeneratorImpl.createGenerator(fs, file, 0, false);
        // WHEN opening the id generator, where the jvm crashes right after
        executeSubProcess(getClass(), 1, MINUTES, file.getAbsolutePath());
        // THEN
        try {
            IdGeneratorImpl.readHighId(fs, file);
            fail("Should have thrown, saying something with sticky generator");
        } catch (InvalidIdGeneratorException e) {
        // THEN Good
        }
    }
}
